U.S.Firm to Unveil Cancer-Fighting Nanotechnology

By Rebecca Lipchitz, The Sun, Lowell, Mass. Knight Ridder/Tribune
Business News

CHELMSFORD, Mass. - A local company working with UMass Lowell
is getting ready for clinical trials on a nanotechnology-based cancer
treatment for prostate and breast cancer.

"We're getting a little too big for our incubator. We're about to pop out of our shell," said Dr. Samuel Straface, CEO of Triton BioSystems, which collaborated with UMass Lowell to develop the treatment.

Representatives from Triton and UMass Lowell, as well as U.S. Rep.
Marty Meehan were scheduled to unveil details during a press
conference Wednesday at Triton's Turnpike Road headquarters.

The company uses technology developed by the Army to create a two-part
cancer treatment in which bioprobes -- nanoscale magnetic spheres
bound to an antibody -- are injected into the body. After the bioprobes attach themselves to cancer cells, the doctor activates the magnetic field, heating up the bioprobes and killing the cancer cells within minutes.

UMass Lowell scientists are working with Triton BioSystems to apply the technology to treatment of other cancers, such as lung, ovarian,pancreatic and renal cancers. U.S. Rep. Marty Meehan secured a $1 million grant from the Department of Defense to fund the project. The Army's research and development department funds projects that use military technology for the advancement of medical technology.

Straface said the money will mostly be put toward the cost of putting the new technology through clinical trials.

The materials are expensive, and the U.S. Food and Drug Administration has strict requirements for testing.

"There are so many standards to meet, it's good for the patient, but very expensive to reach (the market)," Straface said.Triton BioSystems has spent about $5 million of mostly private money on development of the technology since it opened two years ago as an offshoot of Triton Systems. But the cost of development in time and money has been cut in half by the partnership with UMass Lowell,
Straface said.

"We never could have done as much as quickly as we did without that
partnership," he said. "It makes two plus two equal five."

 
Nano Medicine: USA

Nanotech shows great promise on medical application

The science of nanotechnology is rapidly moving from its early beginnings in electronics, computersand telecommunications into the expanding field of nanomedicine.

The emerging nanomedicine has the potential to change medical science dramatically in the 21st century, scientists said at the annual meeting of the American Association for the Advancement of Science (AAAS) in Seattle.

When nanotechnology started in the mid-1990s, it was mainly used to produce smaller and faster semiconductor chips. But in thepast two years, a number of breakthroughs were reported on using the technology to diagnose and treat human diseases.

Nanotechnology works at the atomic and molecular levels, equivalent to 1/100,000th the diameter of human hair.

Nanomedicine integrates technology, biology and medicine, usingtools and materials constructed from molecular and atomic-sized particles too small to be seen with a conventional laboratory microscope, according to Dr. Shuming Nie, professor of biomedical engineering at Emory University and the Georgia Institute of Technology.

Speaking at the nanotechnology forum of the AAAS meeting, Dr. Nie said although nanoparticles are similar in size to biomolecules such as proteins and DNA (deoxyribonucleic acid), they can be humanly engineered to have specific or multiple functions.

Medical applications for nanoparticles will focus on cancer, cardiovascular disease, and neurodegenerative diseases, such as Alzheimers, said Dr. Nie.

The most elementary nanomedical devices will be used to diagnose illness. Mobile nanorobots, equipped with wireless transmitters, might circulate in the blood and lymph systems and send out warnings when chemical imbalances occur or worsen.

Similar nanomachines could be planted in the nervous system to monitor pulse, brain-wave activity, and other functions.

Scientists at the Georgia Institute of Technology have recently developed a tiny nanorobot called "nanospring" structure, which could detect individual molecules and possibly create an extremelysensitive method of detecting cancer.

When the "nanospring" structure encountered even a single cancer-protein molecule, it would send a radio signal through the skin, the researchers said.

More advanced use of nanotechnology might involve nanoparticles to dispense drugs or hormones as needed in people with chronic imbalance or deficiency states.

US scientists have developed semiconductor nanoparticlescalled quantum dots, which can be bound to particular genes and proteins and deliver drug.

The most exciting nanomedicine is nanorobots working as miniature surgeons, which might repair damaged cells, or get inside cells and replace or assist damaged intracellular structures.

At the extreme, nanomachines might replicate themselves or correct genetic deficiencies by altering or replacing DNA molecules.

The American National Science Foundation estimates that the nanomedicine market could be worth 1 trillion US dollars by 2015.Nanomedicine is a priority in the recently released new Roadmap of the US National Institute of Health.

US President George W. Bush signed the 21st Century Nanotechnology
Research and Development Act in December, which invests 3.7 billion dollars over four years starting fiscal year 2005 in research and development programs of nanotechnology. More than half of the money will go to nanomedicine.

But some scientists stressed at the AAAS meeting that it will take 20 to 30 years before people have nanomedical products in their hands.

"That puts us at 2020 or 2025, before nanoscience really becomes part of your life," said Dr. Yi Cui from University of California, Berkeley. Enditem

First robot moved by muscle power

A SILICON microrobot just half the width of a human hair has begun to crawl around in a Los Angeles lab, using legs powered by the pulsing of living heart muscle. It is the first time muscle tissue has been used to propel a micromachine.
This distinctly futuristic development could lead to muscle-based nerve stimulators that would allow paralysed people to breathe without the help of a ventilator. And NASA- which is funding the research- hopes swarms of crawling "musclebots" could one day help maintain spacecraft by plugging holes made by micrometeorites.

Whatever the ultimate applications of the technology, no one was more surprised to see the tiny musclebots finally move than Carlos Montemagno, the microengineer whose team is developing them at the University of California, Los Angeles. He has spent three disappointing years trying, and failing, to harness living muscle tissue to propel a micromachine.

Infineon-Forscher bauen erstmals Leistungshalbleiter mit Nanotechnologie

Forschern des Halbleiter-Herstellers Infineon Technologies AG ist es jetzt zum ersten Mal gelungen, Kohlenstoff-Nanoröhrchen auch für die Herstellung von Leistungshalbleitern zu nutzen. Das berichten jetzt Infineon-Wissenschaftler aus München: Sie zeigen den ersten Schalter aus Nanoröhrchen, der Leuchtdioden oder Elektromotoren steuern kann. Dies gilt als Durchbruch für die Nanotechnik, da Wissenschaftler bisher davon ausgegangen sind, dass sich die winzigen Bauteile in atomaren Größenordnungen nicht für die hohen Spannungen und Stromstärken in Leistungshalbleitern eignen. Mit Leistungshalbleitern aus Kohlenstoff-Nanoröhren könnten Stromschalter eines Tages sehr viel kleiner und preiswerter hergestellt werden als bisher....read the wave

Canadian researcher: Cells can grow on silicon

CALGARY (CP) -- Researchers at the University of Calgary have found that nerve cells grown on a microchip can learn and memorize information which can be communicated to the brain.
"We discovered that when we used the chip to stimulate the neurons, their synaptic strength was enhanced," said Naweed Syed, a neurobiologist at the University of Calgary's faculty of medicine.
The nerve cells also exhibited memory traces that were successfully read by the chip, said Syed, co-author of the landmark study published in February's edition of Physical Review Letters, an international journal….read the wave

PHOTONS ARE REAL

Does light consist of waves or particles? In the early 1920s physicists were
still not certain. Albert Einstein's description of particles or "quanta" of
light--now called photons--had been around since 1905, but at the same time,
over a century of experiments had confirmed that light behaves like water waves.
In May 1923, Arthur Compton of Washington University in St. Louis almost
single-handedly ended doubts about photons with his paper in the Physical Review.

He aimed x rays and gamma rays at electrons and showed that they emerged from the collisions just as would be expected for minuscule billiard balls....read the wave

Mycorrhizal fungi, whose thread-like masses produce the fruiting mushrooms we all know and love, may well be the oldest organisms that reproduce asexually. It's been hard to tell, however, because the cells of these nearly half-a-billion-year-old fungi contain hundreds of nuclei that were thought to be genetically different. UC Berkeley microbiologists have now shown that this is not true, leading the way to a definitive test of whether or not mycorrhizal fungi reproduce asexually... read the wave

Nano Products:

PhoeniX B.V release FlowDB and OperatorDB

The Netherlands: PhoeniX B.V. is proud to announce the release of FlowDB and OperatorDB. These products are developed for the micro and nano technology market. FlowDB is developed to design hierarchic process flows. OperatorDB uses these process flows in manufacturing to gather data from the actual process.
Features of FlowDB:
· Hierachic design of process flows
· Reuse of designs
· Version control
· Arbitrary abstraction levels
Features of OperatorDB
· Interactive logbook facilities
· Active batch control
· Basis for statistical process control
The products can be used as standalone modules. Combining both, however, opens the possibility of using actual data from the factory in new process flow designs. Due to the standardization of information the communication between designers, process engineers and operators is always fast and correct.

Niels Olij (Project leader):"The process related information generation within the micro and nano technology market is very immature. In IC industry comparable tools are available but these are expensive and rather static. That is why most companies and institutes in micro and nano technology currently rely often on in-house solutions; mainly developed due to a lack of professional tools. These internal solutions seem to be cheap and fit internal needs; changing requirements, support and training does make these tools expensive and inflexible though."

Arjen Bakker (CTO):Data storage in a database nowadays is very common practice for all kinds off applications. FlowDB and OperatorDB distinguish themselves by being the first to address real-life cleanroom issues. Being able to (re)use measured data during the design phase of new components or improvements on current design, also reduces "time to market" considerably.

Nano Research:

ATTOGRAM MASS DETECTION
has been achieved…

ATTOGRAM MASS DETECTION has been achieved by Harold Craighead and
his colleagues at Cornell, with prospects of exquisite detection of
very tiny chemical and biological species, possibly with arrays of
detectors. With their lithographically fabricated nanoelectromechanical (NEMS) device, the Cornell researchers can measure the mass of a particle with a sensitivity of 10^-18 grams, far exceeding the precision of a comparable device with femtogram (10^-15 g) sensitivity reported last yearTo get any better measurement of mass you would have to vaporize the particle and shoot its constituent molecules through a mass spectrometer.

At Cornell, mass measurement works this way: when the minuscule
particle is absorbed onto a tiny sliver of silicon it alters the sliver's resonant oscillation.The oscillation in turn is monitored by reflecting laser light off the cantilever. It's as if a particle with a mass of a billionth of a billionth of a gram stepped onto a diving board whose springiness was observed by reflected light. So far Craighead's group has weighed small gold dots and tiny coatings of molecules on the dots, but the goal is to detect and identify viruses. (Previously the same group detected the immunospecific binding of a single bacterium using the
oscillating-cantilever method.

They did this by coating their with a specific antibody and therefore could bind and detect the added mass only of the corresponding antigen.) The mass sensitivity with the present cantilever (4 microns long, 500 nm wide, and at room temperature) is expected to be 0.39 attogram and will only get better as the size of the cantilever is reduced further, extending the sensitivity well into the zeptogram (10^-21 g) range.

Nanobiotech Pioneers Predict Nanomedicine Impact within Five Years

With nanobiotech research growing at an astounding rate -- and funds starting to follow – what are the most promising near-term prospects for nanomedicine?

Predicting which applications will have the resources -- and luck --to succeed is a dicey proposition, experts acknowledge. But NanoBiotech News posed the questions to the field's preeminent pioneers and found that real-world applications of nanomedicine will happen within five years.

Ground-breaking nanotechnology researcher Ralph C. Merkle, Ph.D., and the father of nanomedicine Robert A. Freitas, Jr., JD, are among the industry heavyweights who weighed in with NanoBiotech News on the state of the science and where it's headed.

"Broadly speaking, we are entering a new era in which we can manipulate molecular structures with greater precision," Merkle tells NanoBiotech News.

In some ways, nanomedicine has already entered the clinic in the form of magnetic nanoparticles used as targeted contrast agents for MRI and optical imaging, says Erkki Ruoslahti, Ph.D., MD, professor at The Burnham Institute in La Jolla, CA.

"These show all kinds of promise, not only for diagnostics but for therapeutics," says Ruoslahti, who has conducted seminal research on targeting nanoparticles in vivo.

"The evolutionary spectrum in nanomedicine will start at the sensing and diagnostics end and move into therapeutics over time," predicts Freitas, research fellow at the Institute for Molecular Manufacturing
and author of Nanomedicine, the first book-length technical discussion of the medical applications of nanotechnology and medical nanorobotics.

Diagnostic applications are on a faster track simply because the clinical trials hurdles are fewer and easier, observes Jennifer West, Ph.D., assistant professor in the Department of Bioengineering at Rice
University in Houston and a leading researcher on the use of gold nanoshells. "Scientifically, it makes sense to go for in vitro diagnostics, such as blood tests, and we'll see some nice applications
in diagnostics in the next two to five years."

Freitas adds, "Most of my work is oriented toward the longer term, but if I had to guess, the applications nearest to commercialization are probably the fullerene-related and dendrimer-related drugs," Freitas
says. "The nanoshells are making their way toward commercialization, but the fullerenes and dendrimers are probably closest in terms of somebody making money from a product."

Industry observers and participants alike can stay on top of the nascent field by reading NanoBiotech News every week. Every major nanomedicine development -- from both business and scientific
perspectives -- is covered in this global nanobiotechnology

Prof. Wallace has joined the NCSR team for an eight month period to develop Novel Micropatterned Platforms Utilising Inherently Conducting Polymers.

The aim of this proposal is to use Inherently Conducting Polymers to control,and therefore optimize, how biomolecules interact with each other.

By application of an electronic potential or by chemically changing the reduction/oxidation state, conducting polymers can be used to alter a range of primary molecular interactions which can be further enhanced with the use of specific biological reagents. Using appropriate structures, similar effects maybe induced with optical stimulation.

That was a hoax, but this looks like a real breakthrough in therapeutic cloning. Embryonic stem cells with the same DNA as a donor mother were derived. In spite of great medical promise, it's already stirring up controversy in the Senate, which is deadlocked on whether to ban such research.

But whatever we do in the U.S., it now seems inevitable that reproductive cloning of a human will happen sometime, somewhere. Immortality is an easy sell, and this is as close as you can get.THE UNIVERSITY OF MARYLAND.

Photosynthesis inspires molecular-assembly process

By Chappell Brown, EE Times

Nanotechnologists have recently succeeded in their attempts to build molecular systems based on highly efficient versions of the molecular "machine" that plants use to turn sunlight into energy. Such molecular-assembly machines could be used in many applications, including sensors and other electronic devices.

One recent example is a chemical system devised at Sandia National Laboratory (Albuquerque, N.M.) that creates a wide variety of complex nanostructures from platinum. The system uses the porphyrin molecule, a protein essential to photosynthesis, as a catalyst for depositing platinum on small organic structures called lipids. The process resembles a molecular-scale electroplating technique, except that photons rather than electrons drive the plating operation. …read the wave

CONTROLLING MATERIAL STRUCTURE AT NANOSCALE MAKES BETTER THERMAL INSULATOR

Heat may be essential for life, but in some cases - such as protecting the space shuttle or improving the efficiency of a jet engine - materials with low thermal conductivities are needed to prevent passage of too much heat. As reported in the Feb. 13 issue of the journal Science, researchers have created a better thermal insulator by controlling material structure at the nanoscale.

"We explored ways to control thermal properties in materials by introducing structure on nanometer length scales," said David Cahill, a professor of materials science and engineering and a Willett Faculty Scholar at the University of Illinois at Urbana-Champaign. "By making nanolaminates of dissimilar materials, we found that we could significantly decrease the thermal conductivity because heat
cannot be carried efficiently across the material interfaces."

Cahill, graduate student Ruxandra Costescu and colleagues at the University of Colorado at Boulder first synthesized thin-film nanolaminates composed of alternating layers of tungsten and aluminum
oxide using atomic layer deposition and magnetron sputter deposition. Cahill and Costescu then measured the thermal conductivity of the nanolaminates using a technique called time-domain thermoreflectance.

"The reflectivity of a metal is a very subtle function of its temperature," Cahill said. "By measuring how fast the reflectivity, and therefore the temperature, changes over time, we can determine
the thermal conductivity."

To measure the temperature of such small samples, the researchers use an ultra fast, mode-locked laser that produces a series of subpicosecond pulses. The laser output is split into a "pump" beam
and a "probe" beam. The pump beam heats the sample and the probe beam measures the reflectivity, and hence the temperature.

"By making the individual layers only a few nanometers thick, we produced a nanolaminate material that had a thermal conductivity three times smaller than a conventional insulator," Cahill said. "The high interface density produced a strong impediment to heat transfer."

Heat flow from one material to another is limited at the interface, Cahill said. Heat is carried by vibrations of atoms in the lattice, and some of these lattice vibrations are scattered at the interface and don't get transmitted across the interface.

"In our nanolaminates, vibrations in one material don't communicate well with those in another," Cahill said. "The heavy tungsten atoms are vibrating fairly slowly, but the light aluminum oxide atoms are vibrating quickly. The differences in elastic properties and densities of vibrational states inhibit the transfer of vibrational energy across the interface."

The experimental results suggest that materials engineered with high interface densities may provide a route for the production of thermal insulators with ultra-low thermal conductivities.

The researchers' findings also have some surprising implications for nanomaterials that are intended to perform as high thermal conductors in applications such as dissipating heat from electronic circuits or
sensors. For example, carbon nanotubes - which have been shown to have extremely high thermal conductivities - will not perform well as fillers in composite materials designed to improve thermal transport.

"Nanotubes do not couple well thermally to the surrounding material," Cahill said. "As a result, the heat transport across the nanotube-matrix interfaces will be very limited."…read the wave

Nano Medicine: Nano in Medicine, and its socio-economic implications in Europe

Nanotechnology
In medicine, innovative devices can be developed by arranging atoms in small numbers, almost one by one. Nanotechnology works on a level as small as a millionth part of a millimeter. Tools operating on this tiny scale open possibilities for diagnosis, imaging and implantation that are not thinkable of with conventional techniques.

The EuropeanUnion sponsored network Nanoforum fosters nanotechnology and recently published a report on socalled "smart materials" for medical devices. Such materials are able to help, for example, selecting single cells from blood samples, or to label drug molecules in order to follow their path from the blood into the brain. Apart from these diagnostic purposes, advanced applications as retina implants are seen as well: miniaturised electrodes stimulate the retina cells in the eye and promise to restore a good deal of sight in blind patients.

The report focusses on the social and economic aspects of this new branch of technology, and is complemented with vived examples of current developments. Researchers from Germany, UK, Scandinavia and other countries are interviewed and highlight the pros and cons of the techniques they develop.

The report discusses the developments in the European market and shows a comparison with Japan and the USA: we aren't doing too bad at all. It furthermore gives an overview of existing European networks and European funding bodies that are committed to this 139 billion euros market. National programmes and networks in a number of active countries are presented too. Legislation and regulatory rules that are involved with marketing new products are listed.

Computer scientists develop tool for mining genomic data

Equipped with cutting-edge techniques to track the activity of tens of thousands of genes in a single experiment, biologists now face a new challenge - determining how to analyze this tidal wave of data. Stanford Associate Professor of Computer Science Daphne Koller and her colleagues have come to the rescue with a strategic approach that reduces the trial-and-error aspect of genetic sequence analysis.

``What we`re developing is a suite of computational tools that take reams of data and automatically extract a picture of what`s happening in the cell,`` says Koller. ``It tells you where to look for good biology.``

Koller presented her statistical approach for mining genomic data at a Feb. 14 symposium - ``Machine Learning in the Sciences`` - at the annual meeting of the American Association for the Advancement of Science (AAAS) in Seattle.

Several years ago, before Koller came onto the scene, a new generation of high-throughput assays revolutionized molecular biology. In the most stunning example of this technology, scientists began using thumbnail-sized ``gene chips`` to monitor the activities of thousands of genes at once. In October 2003, Santa Clara-based Affymetrix took this breakthrough to a new level when it began marketing whole-genome chips packed with all 30,000 to 50,000 known human genes. Genome chips can reveal, for instance, that in kidney cells treated with a certain drug, 116 genes spring into action while another 255 get shut off.

But this state-of-the-art DNA microarray technology provides only a single snapshot of the cell. ``It`s a very partial view,`` Koller says.

What scientists really want to know is how groups of genes work together to control specific biological processes, such as muscle development or cancer progression. Unraveling these regulatory networks - for example, determining that Gene A gets activated by Gene B but repressed by Gene C - is a daunting task.

Sifting through whopping amounts of DNA microarray data to cull the hundreds of activator and repressor candidates is actually the easy part. The real challenge is figuring out which of these genes, if any, are biologically meaningful. This requires a bewildering array of hit-or-miss wet-lab experiments that examine protein-protein and protein-DNA interactions among the candidate genes.

Koller`s computational tools will make this scheme less formidable by providing scientists with targeted hypotheses in the form of ``Gene A regulates Gene B under Condition C.`` These predictions are generated from a probabilistic framework that integrates data from a variety of sources, including microarrays, DNA sequences, and protein-protein and protein-DNA interactions.

As Koller sees it, each of these sources offers a glimpse into what is happening in the cell: ``a snapshot from this angle, a shot from another angle, data from a third, and so on.`` Her computational scheme creates ``the best picture we can construct from putting all of these snapshots together.``

The proof of concept for Koller`s targeted hypotheses came in a June 2003 Nature Genetics publication, which described the application of her tools to predict gene regulatory networks in a variety of biological processes in yeast. Three of these predictions were confirmed in wet-lab experiments, suggesting regulatory roles for previously uncharacterized proteins.

``The creativity and computer science perspective brought to these problems by Koller and her collaborators provide a tremendous boost to biology,`` says Matthew Scott, a developmental biologist at Stanford and chair of the scientific leadership council of Bio-X, an interdisciplinary initiative. His research group has used Koller`s approach to identify genes involved in specific processes during embryonic development, to determine which genes are key regulators of other genes and to track changes in gene activities during disease progression.

Scott adds that while the computational methods suggest interesting hypotheses, their ultimate validation relies upon lab experiments.

In the future, Koller hopes to develop her scheme to handle multi-species analysis - for instance, to identify gene regulatory networks that appear in both human and mouse genomes. ``When a regulatory module is conserved across multiple species, that indicates it`s playing a significant role,`` Koller says.

Koller`s collaborators include Eran Segal and Michael Shapira (both of Stanford), Nir Friedman (Hebrew University of Jerusalem), Aviv Regev (Harvard Center for Genome Research), Dana Pe`er (Harvard-Lipper Center for Computational Genetics), Roman Yelensky (Massachusetts Institute of Technology) and David Botstein (Princeton University)….read the wave

PURDUE RESEARCHERS CREATE DEVICE THAT DETECTS MASS OF A SINGLE VIRUS PARTICLE

USA: Researchers at Purdue University have developed a miniature device sensitive enough to detect a single virus particle, an advancement that could have many applications, including environmental-health monitoring and homeland security.

The device is a tiny "cantilever," a diving board-like beam of silicon that naturally vibrates at a specific frequency. When a virus particle weighing about one-trillionth as much as a grain of rice lands on the
cantilever, it vibrates at a different frequency, which was measured by
the Purdue researchers.

"Because this cantilever is very small, it is extremely sensitive to added mass, such as the addition of even a single virus particle," said Rashid Bashir, an associate professor of electrical and computer engineering and biomedical engineering.

Findings are detailed in a paper to appear next month in Applied Physics Letters, a journal published by the American Institute of Physics. The paper, which is likely to appear in the weekly journal's
March 8 issue, was written by doctoral student Amit Gupta, senior research scientist Demir Akin and Bashir, all in Purdue's School of Electrical and Computer Engineering.

The work, funded by the National Institutes of Health, is aimed at developing advanced sensors capable of detecting airborne viruses, bacteria and other contaminants. Such sensors will have applications in areas including environmental-health monitoring in hospitals and homeland security.

"This work is particularly important because it demonstrates the sensitivity to detect a single virus particle," Gupta said. "Also, the device can allow us to detect whole, intact virus particles in real
time. Currently available biosensing systems for deadly agents require that the DNA first be extracted from the agents, and then it is the DNA that is detected."

The next step will be to coat a cantilever with the antibodies for a specific virus, meaning only those virus particles would stick to the device. Coating the cantilevers with antibodies that attract certain
viruses could make it possible to create detectors sensitive to specific pathogens.

"The long-term goal is to make a device that measures the capture of particles in real time as air flows over a detector," Bashir said.

Scientists are striving to create "lab-on-a-chip" technologies in which miniature sensors perform essentially the same functions now requiring bulky laboratory equipment, saving time, energy and materials.

Thousands of the cantilevers can be fabricated on a 1-square-centimeter chip, Akin said.

The Purdue researchers used the device to detect a particle of the vaccinia virus, which is a member of the Poxviridae family and forms the basis for the smallpox vaccine.

The cantilever is about one micron wide - or about one-hundredth the width of a human hair - 4 microns long and 30 nanometers thick. A nanometer is a billionth of a meter, or roughly the length of 10 hydrogen atoms strung together.

"This cantilever mechanically resonates at a natural frequency, just like anything that vibrates has a natural frequency," Bashir said. "What we do is measure the natural frequency of the cantilever, which
is a function of its mass. As you increase the mass, the frequency decreases. And the way to increase the sensitivity is to make that starting mass very, very small."

A single vaccinia virus particle weighs about 9 femtograms, or quadrillionths of a gram.

"So, if a grain of rice weighs a couple of milligrams, one of these virus particles weighs about one-trillionth as much," Bashir said.

Because the cantilevers are mechanical parts measured primarily on the scale of microns, or millionths of a meter, they are called "micromechanical devices."

The researchers created the cantilever using the same technology used by the semiconductor industry to etch circuits in electronic chips. Silicon is deposited as a blanket onto the surface of a wafer and then formed into patterns during numerous steps, including chemical etching. In this case, a cantilever is formed instead of a circuit.

In addition to funding from NIH, facilities in Purdue's Birck Nanotechnology Center were used to carry out the experiments. ...read the wave

RULE-BREAKING' MOLECULE COULD LEAD TO NON-METAL MAGNETS

WEST LAFAYETTE, USA Purdue University scientists have uncovered an unusual material that could lead to non-metallic magnets, which might be lighter, cheaper and easier to fabricate than magnets made of metal.

A team of researchers, including Paul G. Wenthold, has analyzed a radical hydrocarbon molecule whose electrons behave differently than they should, according to well-known principles. The compound is not the only molecule that exhibits such odd behavior in its surrounding cloud of electrons, but it is the first to be discovered that does not include a transition metal.

"In that respect, this is a unique exception to the electron-behavior rule, and it might help chemists think more clearly about where other exceptions lie," said Wenthold, an assistant professor of chemistry in
Purdue's School of Science. "Designing materials with novel properties depends on understanding the forces at work inside their molecules, and understanding the structure of this exceptional molecule could lead to new tools for material design."

The research, which Wenthold conducted with Anna I. Krylov of the University of Southern California and members of both their research groups, appears in today's (2/ 2) issue of Angewandte Chemie International Edition, a major European chemistry journal. The team deduced the structure of the compound using advanced techniques, including mass spectrometry.

Radical molecules, which contain unpaired electrons and are thus more reactive than molecules without them, have gained household notoriety primarily because so-called "free radicals" in the bloodstream can
damage healthy cells. While the molecule Wenthold's team has investigated is not found in the body and has no household name - it is referred to only by its chemical description, 5-dehydro-1,3-quinodimethane - it has a property that would raise the eyebrows of any observant student in a first-year chemistry course. The surprise stems from the uncommon way its three unpaired electrons arrange themselves around the nuclei in the molecule's atoms - an arrangement that students learn is virtually fundamental.

"It's called Hund's Rule," Wenthold explained. "It says that unpaired electrons line up facing the same direction when they arrange themselves around the molecular center. You might think of them as
three-ring binders lying flat on shelves: You want to be able to read the labels on all of their spines, so you lay each binder flat with its spine pointing outward."

Paired electrons, he explained, would resemble two binders stacked one atop another; if their spines were both facing the same way, the top face of the upper binder would not form a flat surface, and it would tend to slide off the lower binder. None of a radical's unpaired electrons is constrained by this need to face the opposite direction, as they all have their own "shelves," or quantum energy levels.

"Nonetheless, one of the three unpaired electrons in our molecule faces the opposite direction," Wenthold said. "Since this is the first time we've ever seen this happen in an organic triradical, it opens up a few
new possibilities for materials designers."

Krylov said the possibilities might include the building blocks for molecular magnets.

"People are already trying to build magnets from materials other than metals, such as the polymers that form plastic," she said. "Since magnetism is related to the behavior of unpaired electrons, this compound could be used as a building block for such polymers, leading to non-metallic magnets. It could extend a materials scientist's options."

The National Science Foundation (NSF)'s Tyrone Mitchell said that non-metallic magnets might have significant advantages over metal ones.

"Non-metal magnets would have several conceivable advantages," said Mitchell, who is program director in the NSF's chemistry division. "If we can find ways to magnetize hydrocarbons, for example, they would weigh less than metallic magnets, making them attractive to the space program and other commercial applications in which weight is always a concern. And since the raw materials would also be cheaper and easier to fabricate than metal substances, such magnets could conceivably save
money in the long run."

Wenthold and Krylov cautioned that such possibilities are only speculation for the moment, and for now the major significance of the find is the fundamental knowledge it provides.

"We still have a lot to learn about molecules such as this one," Wenthold said. "We have a long list of steps that will follow this one, such as comparing this molecule's properties with one that does not
have its unpaired electrons facing different directions. But the unique property this substance exhibits will be of interest in its own right, even before we come up with any actual applications for it. It is one
thing to discover magnets - designing them is far more difficult and requires an understanding of what makes them magnets in the first place."

CARBON NANOTUBE GEL, the first example of a liquid crystalline material consisting of single-walled nanotubes, has been made by physicists at the University of Pennsylvania. Basically the gel is a mass of half-micron long nanotubes, aligned like little logs along a single direction, in a polymer matrix. The gel exhibits hallmark properties of a nematic liquid crystal (in which rod shaped molecules are aligned) including optical anisotropy (birefringence) and topological defects. The gel's anisotropic characteristics and its sensitivity to changes in solvent quality might make it a candidate for novel applications. It could be useful, for example, as an osmotic or an electrical actuator in which changes in electrical field or salt concentration produce volume and shape changes. The gel was made by coating the nanotubes with surfactant chemicals and mixing in polymers which form a cross-linking network among the tubes. Next the volume was compressed. The resultant densities of isolated single-wall nanotubes are higher than can be produced in simple aqueous suspensions. (Islam et al., Physical Review Letters, upcoming article;

DUPONT DONATES NANOTECHNOLOGY PATENTS

The University of California, Davis, College of Engineering has received a collection of patents and other intellectual property from DuPont on using nanotechnology to generate electron beams. The donation will support work in the Vacuum Microelectronics group led by Charles E. Hunt, professor in the Department of Electrical and Computer Engineering.

The donation includes: eight granted U.S. patents and current U.S. patent applications on field-emission vacuum microelectronics; multiple foreign patents and pending applications; other company technical information; support equipment; and funds to support graduate student research in Hunt's laboratory.

Hunt's laboratory applies nanotechnology to build tiny structures, hundreds of times smaller than the thickness of a human hair, that can confine enormous electric fields in a very small volume of material. This material then emits electrons that can be focused into a beam. These "field-emission" devices have numerous emerging applications ranging from high-efficiency lighting to novel biomedical devices, nanoscopic X-ray sources, cathode ray tubes and microwave devices, Hunt said.

The UC Davis researchers will be able to develop and add to the existing patents and license them to other companies or to startup companies spun off from UC Davis. Any future royalties or licensing fees will benefit the University of California.

"We are immensely pleased by the generous donation from DuPont," said Enrique Lavernia, dean of the College of Engineering at UC Davis. "It allows us to build on an area in which the college already excels,and it is a vote of confidence on the part of an important industrial partner in our ability to make the best possible use of the patents. We know that our researchers in the Department of Electrical and
Computer Engineering are poised to build on this gift.

Researchers in Colorado (USA ) have discovered a new form of atomic matter, a fermionic condensate unlike anything seen before.

To approach this conceptually-difficult but physics-rich topic, we will proceed in several parts: providing a quantum background, defining the word "degeneracy," summarizing the new atomic state, and finally
assessing the advantages of the new state.

1. Quantum background. In exploring the exotic landscape ofquantum gases, physicists have lavished much attention on bosonicatoms (atoms whose total spin has an integer value, such as 0 or 1or 2). In 1995 scientists succeeded in cooling (bosonic) atoms sothat in a quantum sense the atoms began to overlap, at which pointthey really could not be distinguished and had, in effect, becomepart of a single quantum entity called Bose Einstein condensate(BEC). Fermions (possessing half-integer spins, such as 1/2 or 3/2
or 9/2), whether elementary particles like electrons and quarks, orwhole atoms (and in determining whether an atom is a boson orfermion one has to add up the spins of all its constituent protons,neutrons, and electrons), do not act like bosons. The Pauliexclusion principle dictates that no two identical fermions may occupy the same quantum state. Most of chemistry here on Earth andelsewhere is dictated by the simple Pauli rule: electrons fillatomic orbitals in such a way that no two electrons have exactly thesame quantum values. Partially filled orbitals determine what kindof chemical affinity that atom will have. Note that fermion atomsare not precluded from interacting in ordinary chemical reactions(the atoms have differing nuclear and electronic internalc onfigurations). But they may not enter into an extensive BEC kind of quantum condensate where the atoms do possess the same quantum attributes.

2. Degeneracy. Pauli is on duty at all times, but he chieflymanifests himself in a quantum setting, such as in the orbitalswithin an atom or in the chilled molasses of a microkelvin-levelatom trap. In this rarefied realm, bosons can all fall into that singular BEC state. All having the same energy, these atoms are
said to be degenerate. With fermions, it's quite different. In aquantum setting---whether electrons moving through a crystal or fermion atoms chilled in a trap, fermions are obliged to fill, one by one, all the different possible quantum energy states, starting at the low end. On an energy level diagram, the fermions look as if they were perching on the rungs of a ladder, filling all the rungs singly. (The uppermost rung is called the fermi energy and the temperature that corresponds to that energy is called the fermi temperature.)

Commonplace example: the free-roaming electrons in a metal crystal, even at room temperature, are obliged to assume a set of discrete quantum-allowed energies in this way. These electrons are said to constitute a degenerate fermi gas. In the fermion context, "degenerate" means that the particles fill up the plenum of possible energy states. Creating such a gas of degenerate fermion atoms proved more difficult to make than a degenerate (BEC) gas of boson atoms. In fact, a degenerate fermi gas was first accomplished
only in 1999 (www.aip.org/enews/physnews/1999/split/pnu447-1.htm) in an experiment by Deborah Jin and her NIST/JILA colleagues, the same lab where the new results have been performed. By the way, although
physicists had long assumed the Pauli principle would apply to atoms (composite objects) as well as to electrons (truly elementary particles), it was only in recent work that this was demonstrated experimentally.

3. New state of matter. Fermions, if you pair them, can become bosons. And in that way, fermions can enter pairwise into a quantum condensate. There are, however, a whole spectrum of pairing mechanisms. At one extreme is the case where the atoms pair strongly, after which they can (as molecules) collapse into a Bose Einstein condensate (BEC). At the other end of the spectrum the atoms can pair weakly, or more to the point, combine in an unbound but correlated state analogous to the Cooper pairs of electrons that form the essence of quantum currents in superconductors or the pairs of helium-3 atoms that constitute a superfluid. In previous months a number of labs have reported forming condensations of
strongly-bound molecules

(see www.aip.org/enews/physnews/2003/split/663-1.html ). Now Deborah Jin and her colleagues Cindy Regal and Marcus Greiner at NIST and the University of Colorado report making great progress in moving across the plain between the BEC and BCS pairing alternatives. The type of pairing can be adjusted by subtly altering the strength of an external magnetic field. The NIST researchers, who cool potassium-40 atoms to microkelvin temperatures, are at the cross-over region: they are not at the BEC regime because the applied magnetic field would not permit the kind of pairing one needs for a BEC condensate. Also they can affirm that they are not in the BCS regime either because the strength of the interaction among atoms is too strong for the kind of weak Cooper pairing that occurs in superconductivity or helium-3 superfluids.

This new condensed form of atomic matter should not be thought of merely as a way station between the BEC and (weak) BCS pairing alternatives, but as a unique state in its own right. Eric Cornell (also at NIST but not part of Jin's group), who won a Nobel prize for his part in the discovery of BEC, describes the new NIST state as "a dramatic new sort of fermionic condensate, basically Cooper pairing in the strong-field limit."

4. Assessment. One of the goals in pursuing this research is the chance to form novel types of Cooper pairs or superfluids, and possibly to custom make different kinds of superconductivity. In these cold fermi gases the interactions (and the strength of the pairing) can be adjusted by turning a knob (changing the magnetic field), which is more than you can say about conventional superconductivity, metallic or ceramic. Here is one hint that this work might lead to warmer, even room temperature, superconductivity: In the new potassium fermionic condensate the ratio of transition temperature (at which condensation of pairs
occurs) to fermi temperature is about 1 to 5. In conventional low-temp superconductors the ratio is 1 to 1000 (or even 100,000).

``The light shines brilliantly these days at the Stanford Synchrotron Radiation Laboratory (SSRL),`` said U.S. Secretary of Energy Spencer Abraham. ``The start-up of SSRL`s new synchrotron light facility, SPEAR3, guarantees a world-class program in x-ray science for years to come.``

SPEAR stands for Stanford Positron Electron Asymmetric Ring. SPEAR3 was formally opened at a dedication ceremony at the Stanford Linear Accelerator Center (SLAC) on Jan. 29. It incorporates the latest technology - much of it pioneered at SSRL and SLAC - to make it competitive with the best synchrotron sources in the world.

Some 2,000 scientists from around the country will use SPEAR3`s extremely bright x-ray light each year to illuminate the long-kept secrets of materials, chemical and biological matter.

Synchrotron light has revolutionized our view into the sub-microscopic world and has contributed to major innovations in fields such as solid-state physics, materials science, environmental sciences, structural biology and chemistry. Synchrotron light is created when electrons traveling the speed of light take a curved path around a storage ring, a structure in which high-energy particles can be circulated many times and thus ``stored.`` The electrons emit electromagnetic light in x-ray through infrared wavelengths. The resulting light beam has characteristics that make it ideal for revealing the intricate architecture and utility of many kinds of matter.

``This facility will be crucial to advancing the field of structural biology, which is growing in importance to the NIH [National Institutes of Health] mission, by enabling cutting-edge targeted drug design projects and major efforts such as the Protein Structure Initiative and the Structural Biology arm of the NIH Roadmap,`` said Dr. Elias Zerhouni, NIH director. ``From its very genesis as a joint project between NIH and DOE [Department of Energy], this new facility exemplifies the collaborative nature of science and the productive cross-fertilization between biological and physical disciplines.``

Said SSRL physicist John Arthur: ``SPEAR3`s brilliant x-ray beams provide the ability to study smaller objects at higher resolution. In many cases the greater brightness at SPEAR3 will also enable researchers to take their data faster, do more difficult experiments and use smaller samples of material.``

Noted Abraham: ``This is the first time the Department of Energy and the National Institutes of Health have joined in funding an accelerator research facility.``

Thirty years ago, SSRL was among the first laboratories in the world to use synchrotron produced x-rays for studying matter at atomic and molecular scales, and the first to offer beam time to a broad community of scientists from academic, industry and government labs submitting research proposals for peer review. The original SPEAR ring, built for particle physics programs at SLAC, yielded two Nobel prizes and provided fertile ground for innovating synchrotron techniques and making important discoveries. SPEAR3 is a complete rebuild and upgrade of the SPEAR2 ring, which was the original ring adapted for improved performance in synchrotron radiation research.

Lines extend from the ring to carry synchrotron radiation to experimental stations. The new ring has the capacity to easily add eight to 10 more beam lines, with associated experimental stations, beyond the existing 11 beam lines. A $14.2 million gift from the Gordon and Betty Moore Foundation to the California Institute of Technology, announced Jan. 28, will allow scientists at Caltech and Stanford to collaborate on the building of a designated beam line at SPEAR3 for structural molecular biology research. The exceptional quality and brightness of SPEAR3`s x-ray light is perfectly suited to studying complicated biological systems.

The first electron beams circulated in the new SPEAR3 ring in mid-December 2003, and the first experiments are scheduled to begin in March.

``SPEAR3 is a remarkable resource that will enable state-of-the-art science in numerous fields,`` said SSRL Director and Stanford Professor Keith Hodgson. ``The $58 million project was completed on time and on budget. I thank the people whose extraordinary teamwork made the project successful. In a remarkable accomplishment, the old accelerator was dismantled, a new tunnel floor poured, SPEAR3 installed and commissioned, and users back online - all within a mere 11 months.``

MOLECULAR FOUNDRY GROUNDBREAKING MARKS BERKELEY LAB'S LEAP INTO THE NANOREVOLUTION

BERKELEY, CA ,  USA. The term “Molecular Foundry” suggests a place where objects are forged and new materials are molded. Like the foundries of the industrial revolution, this new concept, on a nanoscale, promises to revolutionize the way the world works. It begins at the Department of Energy’s Lawrence Berkeley National Laboratory – ceremonially, on Friday, Jan. 30).

 

That’s when ground was turned for the official beginning of construction on a six-story, $85 million, 94,500-square-foot research building that will be one of the centerpieces of the DOE’s Nanoscale Research Program. Berkeley Lab’s Molecular Foundry is one of five DOE research centers to be constructed over the next few years.

 

“This facility will assist scientists in reaching new frontiers in the study of nanoscale research and its practical application,” Secretary of Energy Spencer Abraham said. “It represents a beginning of a revolution

in science, opening up a broad array of innovation in materials science, biology, medicine, technologies for environmental research and national security.

 

“Berkeley is blessed with tremendous resources, such as the national supercomputing center (NERSC), the Advanced Light Source, and the National Center for Electron Microscopy,” he added. “All will be

instrumental in the revolution in science offered by the Molecular Foundry.”

 

“Nanoscale research will, in many respects, represent the new building blocks for new technologies and applications across the science and industry spectrum,” said Berkeley Lab Director Charles Shank.

“Understanding the properties of materials on the tiniest scale will have an impact on everything, from medicine to manufacturing.”

 

Nanoscale research enables scientists literally to build novel structures atom by atom. The fundamental properties of materials and systems are established at the nanoscale.  Nanomaterials, typically on

the scale of billionths of a meter, or 75,000 times smaller than the width of a human hair, offer different chemical and physical properties than the same materials in bulk form, and have the potential to form the

basis for new technologies. This especially includes the realm of molecular biology.

 

Berkeley Lab’s Molecular Foundry – actually the research building around which Foundry programs will be developed – will include six facilities available to users from around the world. These include labs and experts devoted to inorganic nanostructures; nanofabrication; organic, polymer/biopolymer synthesis; biological nanostructures; imaging and manipulation; and theory. Its focus will be on the design, synthesis and characterization of both “soft” (biological and polymer) and “hard” (inorganic and microfabricated) substances and the integration of these into complex assemblies.

 

The SmithGroup of San Francisco designed the structure, which will follow the contours of a hillside site between a materials research building and the microscopy center. Construction will be coordinated by

Rudolph and Sletten, Inc. of Foster City. When completed in 2006, the Foundry building will house more than 200 scientists and support staff, using state-of-the-art instrumentation for imaging and manipulation.

 

Berkeley Lab’s facility is one of five in the DOE’s proposed Nanoscience Research Program; others will be developed at Oak Ridge National Laboratory, Brookhaven National Laboratory, Argonne National Laboratory

and Sandia National Laboratories/Los Alamos National Laboratory.

 

The possibilities to grow out of this and other initiatives dedicated to the field of nanoscience are virtually limitless. Some potential outcomes that have been suggested include:

 

*  Carbon nanotubes -- sheets of graphite rolled into extremely narrow tubes a few nanometers in diameter– could be the possible building blocks of future electronic devices.

 

*  Nanotechnology may one day enable the detection of disease on the cellular level and the targeting of treatment only to tissues where it is needed in a patient’s body, potentially alleviating many unpleasant

and sometimes harmful side effects.

 

*  Nanomanufacturing of parts and materials “from the bottom up”—by assembling them on an atom-by-atom basis—may one day be used to reduce waste and pollution in the manufacturing process.

 

*  Nanosensors already are being developed to allow fast, reliable, real-time monitoring for everything from chemical attack to environmental leaks.

 

*  Woven into a cable, carbon nanotubes could provide electricity transmission lines with substantially improved performance over current power lines.

 

*  Certain nanomaterials show promise for use in making more efficient solar cells and the next-generation catalysts and membranes that will be used in hydrogen-powered fuel cells.

 

U.S. Rep. Mike Honda, D-San Jose, was featured speaker at the groundbreaking ceremony. Honda was co-sponsor of the Boehlert-Honda Nanotechnology Act of 2003, which authorizes $3.7 billion over the next

three years for nanotechnology research and development programs

FEDERAL NANOTECH CONFUSION SPREADS TO CALIFORNIA MICHAEL CRICHTON MISTAKEN FOR RICHARD FEYNMAN

A report released on January 20, 2004 in Sacramento indicates that
U.S. federal confusion over nanotechnology's original goal has spread to the state of California, where the concept originated. The report, "Nanoscience and Nanotechnology: Opportunities and Challenges in California,"was released yesterday at a meeting of the state's Joint Committee on "Preparing California for the 21st Century."


Christine Peterson, president of the California-based Foresight Institute, addressed the Committee meeting: "The original goal for nanotechnology -- systems of molecular machines, building cleanly with atom-by-atom precision, as described by Nobel physicist Richard Feynman -- is entirely absent from the report. His name does not even appear.Instead, the concept of molecular machines appears only in the form of 'plagues of self-replicating nanobots,' as in Michael Crichton's thriller Prey. The environmental benefits of molecular manufacturing may be needlessly delayed by this confusion." Foresight is the leading public interest group in nanotechnology.


Ray Kurzweil, a National Medal of Technology winner who serves on Foresight's Board of Advisors, commented: "While the report has its visionary elements -- such as projecting 'intracellular intelligent machines' within 15 years -- the omission of molecular machine systems is extremely disappointing and, if not corrected, may contribute to the state losing its natural lead in this area."


Prof. Ralph Merkle, a winner of the Foresight Institute Feynman Prize in Nanotechnology and current chair of the Prize Committee, stated, "This confusion was distressing enough when it first appeared in Washington, but it is far more so in California, where Feynman set the goal in 1959 at Caltech. It's true that Caltech and Hollywood - where Michael Crichton thriller films are made -- are not far apart geographically, but Californians should know the difference."

 

Building with atomic precision using molecular machine systems, also known as molecular manufacturing, is seen as a key technology for the environment, medicine, and defense. "This proposed technology -- the 'nanofactory' - is our best hope for ending chemical pollution as we know it today," said Peterson. "California's strengths in design, systems engineering, and software -- combined with its strong interest

in restoring the natural environment -- give it an edge in this area. The state's proposed Nanotechnology Research and Workforce Advisory Council should include molecular manufacturing as a major focus." ...read the wave

A Tale of Two Nanotechs

It's the best of times for nanotechnology. Or is it the worst of times? There's evidence in both directions.
On the upside, nanotechnology is becoming real, with increasing numbers of applications and breakthroughs. Even a dedicated observer of the field (like, er, me) can't keep up with all the new research and applications. And while we're a long way from Drexlerian nanobots, we're a long way beyond mere gimmicks like stain-resistant nano-pants, too.read the wave
