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

NASA SCIENTISTS USE YEAST TO UNDERSTAND MICROGRAVITY

NASA scientists will study brewers yeast --typically used to make bread and beer -- to better understand how microgravity affects genes, and gain insight into the genetic basis of how humans respond to microgravity.

Deeper understanding of the molecular mechanisms of yeast's genetic response to microgravity will help NASA scientists identify which genes enable cell survival. Molecular biologists have added 'signature tags' to every gene in the yeast genome, so that the effects of microgravity on each gene can be studied. The benefit of using yeast cells is that it serves as a benchmark microbe for biological research studying human or other mammalian cells that have a very large and complex set of genes.

"Understanding gene expression patterns and how they are altered when cells are grown in the low-gravity, or microgravity, environment inside the International Space Station will help scientists learn how humans respond to gravity," said principal investigator Dr. Cheryl Nickerson from the Tulane University Health Sciences Center, who is working with co-investigator Dr. Tim Hammond of Tulane University and the Veterans Affairs Medical Center in New Orleans. 

Two
Yeast Group Activation Packs (GAP) that hold the yeast cultures, liquid growth medium and fixative used to preserve cells in space will be flown onboard the Russian Progress launch vehicle 13P scheduled to launch on Jan. 29 from the Baikonur Cosmodrome in Kazakhstan. After a two-day flight, the payload will be transferred to the International Space Station, where the experiment will remain for several months.

"This experiment will be among the first set of U.S. biological experiments that will be sent into space since the Columbia accident," said Dr. Beverly Girten, chief of the Science Payloads Operations Branch and small payloads project manager at NASA Ames Research Center, Moffett Field, Calif.  

To activate the experiment, an International Space Station crewmember will insert a hand crank into the top of the GAP. Turning the crank will cause the yeast cells to mix with the liquid growth solution and begin growing. Following the growth period, the hand crank will be inserted into the top of the GAP again and turned, which will allow fixative to mix with the growing yeast colony, thus preserving the cells.

The preserved cells will be contained within the GAP for up to one year following experiment activation. They will be returned to Earth where scientists will compare them to identical yeast cells grown inside a ground control unit. By comparing the yeast genes expressed during ground-based growth with those expressed when the organism is grown in space, scientists can determine how microgravity alters the genetic expression profile and survival of cells.

"This experiment is a collaborative effort between peer-reviewed investigators funded through NASA's Office of Biological and Physical Research's (OBPR) Fundamental Space Biology Division, commercial groups working through OBPR's Space Product Development, and several NASA centers," said Girten. "This shared effort is particularly important since the shuttle fleet is not flying and there are limited opportunities to conduct science in space right now."  …read the wave

NanoHorizons announces Matrix-less MALDI now available for Fast, Cost Effective Analysis of Small Molecules

State College, PA, USA : NanoHorizons, an emerging leader in nanoscale material and device technologies, and Kratos Analytical (a wholly owned subsidiary of Shimadzu Corporation), a world leader in Mass Spectrometry, announced the commercial introduction of a fast, precise technique for small molecule analysis today.  Kratos Analytical will offer the NanoHorizons’ QuickMass™ targets, which are used to identify low molecular weight compounds in MALDI (Matrix Assisted Laser Desorption Ionization) mass spectrometers, through Shimadzu Biotech, a business unit of Shimadzu Corporation.  Users of the Axima-QIT™ and Axima-CFR™plus line of mass spectrometry systems will soon be able to realize the benefits of high throughput and lower cost from using disposable, matrix-less, QuickMass™ targets for small molecule analysis.  QuickMassTM targets increase selectivity and reduce cross-contamination concerns for small molecule detection in MALDI-type mass spectrometers.

“QuickMassTM targets are a breakthrough in mass spectrometry: they provide clean and reproducible low molecular weight spectra by eliminating the matrix compound used to help laser desorption/ionization in a MALDI mass spectrometer.  This dramatic improvement is due to the QuckMassTM target’s non-porous, thin film surface, which adsorbs and transfers the laser energy to the sample molecules.  Accordingly, the interfering background matrix peaks that are commonly observed with MALDI MS are not present.  Also, the lack of surface porosity prevents low mass contaminant trapping” says Dr. Stephen Fonash, founder and Chairman of NanoHorizons

Weihnachten ist vorbei, aber die Erinnerung bleibt: Gerade noch leuchten die Lichter am Baum so schön, da kündet ein kurzes Flackern von Unheil und schon geht die gesamte feierliche Beleuchtung aus.

NEW DRESSING FOR WOUNDS DEVELOPED AT HEBREW  UNIVERSITY PROMISES FASTER AND IMPROVED HEALING

A novel wound dressing made of genetically engineered human collagen that will enable faster and improved healing of injuries has been developed by researchers at the Hebrew University Faculty of Dental Medicine.


Collagen is the most abundant protein in the animal kingdom, including humans. It is the major constituent of connective tissues – tendons, skin, bones, cartilage, blood vessel walls and membranes. Collagen fibers are the “warp and woof” of these connective tissues and are responsible for keeping all the body’s organs and tissues in their correct functional structure.

There are different collagen-containing preparations on the market today made for treating wounds, for use in dentistry implants, and in cosmetics. All of them use collagen made from animal tissues, which requires specific adaptation in order to eliminate immunological rejection or to prevent microbiological infection.

The dressing developed at the Hebrew University incorporates an inner layer of genetically engineered, human recombinant collagen. This material becomes a soluble, readily enzymatically degradable molecule in the wound tissue. The molecular fragments that are thus formed have been shown to play a pivotal role in the healing process. An outer layer, also of biological origin, is provided in the wound dressing to provide initial protection prior to release of the delicate collagen layer.

Preliminary animal experiments with the new dressing have shown substantially faster and better healing, with rapid formation of new collagen fibers, than has been possible using older methods.

The new dressing is the fruit of many years of experimentation with collagen in the laboratory of Prof. Emeritus Shmuel Shoshan of the Connective Tissue Research Laboratory of the Hebrew University Faculty of Dental Medicine. Prof. Shoshan is the inventor and chief scientist of Dittekol Ltd., a company formed in cooperation with the Hebrew University’s Yissum Research Development Company, to commercialize the new wound dressing. The company is now negotiating with investors for further development.

It's expected that the teams will consider the probe a lost cause if it can't be reached by March.

Nano Europe :

INP Grenoble, Politecnico di Torino and Ecole Polytechnique Fédérale de Lausanne are joining forces to set up an international course for nanotechnology engineers.

 


Products implementing microtechnology are already omnipresent in daily life, but there is still plenty of scope for miniaturization. To go much further we must master micrometerand nanometer-scale technologies, for which specially trained engineers are essential. Nanotechnology is equally vital for developing instrumentation, not to mention the actual teaching of nanoscience. 

 

The aim of the interna-tional engineering degree in nanotechnology is to prepare graduates for such work. Successful applicants will benefit from the high-grade teaching and research capability of three European universities (Grenoble, Lausanne and Turin). The four-semester course will include modules on microsystems, microelectronics design and nanotechnology, in three languages (English, French and Italian). Students will spend a semester at each university and a fourth doing an assignment in industry or a research laboratory, making a flying start to their career. Teaching in Grenoble will be based at ENSERG(12) and ENSPG(13), both part of INP Grenoble. 

 

 

Between 45 and 60 places will be open in September 2004 to students from the three universities and the first batch will graduate in July 2006. This highly original course will qualify for a joint engineering degree in nanotechnology awarded by INP Grenoble, EPFL and Politecnico de Torino. It will be the first course of its kind in France.

New g-2 Measurement Deviates Further From Standard Model

 

UPTON, NY USA - The latest result from an international collaboration of

scientists investigating how the spin of a muon is affected as this

type of subatomic particle moves through a magnetic field deviates

further than previous measurements from theoretical predictions. The

result strengthens the challenge this experiment, known as muon g-2,

first posed to the so-called Standard Model of particle physics in

February 2001 (based on data collected in 1999), and then backed with

a more precise result in July 2002 (based on data collected in 2000).

 

The new measurement, which has been submitted to Physical Review

Letters, was announced today at the U.S. Department of Energy's

Brookhaven National Laboratory, where the experiment was conducted by

scientists from Brookhaven and 11 other institutions in the United

States, Russia, Japan, The Netherlands, and Germany. Based on data

collected in 2001, it is the first precise measurement of how

negatively charged muons "wobble" in the magnetic field; the two

prior results were for positively charged muons. The precision of the

new result matches the combined precision of the previously reported

results.

 

All three results are in good agreement with one another and with a

long-standing theoretical prediction of the so-called PCT Theorem

that particles and antiparticles should wobble at the same rate in a

magnetic field. But when compared with the latest Standard Model

predictions for the g-2 value, the new experimental result differs

from the most direct theory calculation by 2.8 standard deviations,

and from a somewhat more indirect theory calculation by 1.7 standard

deviations, making this the most significant deviation to date

between experiment and theory. When the positive and negative muon

results are combined, the result differs from the direct theory

calculation by 2.7 standard deviations, and from the indirect theory

calculation by 1.4 standard deviations. The two theoretical

predictions are in significant disagreement with one another and have

been under close scrutiny by the theory community for several years.

The related theory issues are gradually being clarified and may get

fully resolved soon.

 

Boston University physicist Lee Roberts, spokesperson for the muon

g-2 experiment, said, "The measurement of this property, the

anomalous magnetic moment of the muon, is a very sensitive test of

the validity of the Standard Model, and is also sensitive to new

physics beyond the Standard Model." The Standard Model seeks to

describe the effects of three of the four known forces on all

subatomic particles. "The fact that our measurement continues to

deviate from what that theory predicts may be an indication that we

are seeing new physics beyond the Standard Model," Roberts said.

 

While physicists have known for some time that the Standard Model is

incomplete, the correct extension to this theory is still a matter of

speculation, with one leading candidate being supersymmetry - a

theory that predicts the existence of yet-to-be-discovered companion

particles for all the known subatomic particles. "One reason there

has been so much interest in our experiment is that the rate at which

muons wobble in a magnetic field would be affected by the presence of

new physics, such as supersymmetric particles, if they exist," said

Roberts. "Historically, muon g-2 has provided an important constraint

on new theories. Our experiment is now fourteen times more precise

than the experiment done at CERN [the European laboratory for

particle physics] in the 1970s. This precision places important

restrictions on potential new theories."

 

Added William Marciano, senior theoretical physicist at Brookhaven

Lab, "The recent g-2 result strengthens the case for new physics

effects with supersymmetry, a leading candidate, but it is by no

means definitive. Continued scrutiny of theory and further running of

the experiment are imperative."

 

Background on previous g-2 results

 

The Standard Model of particle physics is an overall theory of

particles and forces that has withstood experimental challenge for

some 30 years. In February 2001, the muon g-2 collaboration published

a finding that deviated from the value predicted by the Standard

Model. The result of that experiment, which like the current one, was

performed at Brookhaven's Alternating Gradient Synchrotron, had a one

percent statistical chance of being explained by the theory as it was

understood at that time.

 

After that announcement, perhaps because of the startling

experimental result from Brookhaven, many theoretical and

experimental physicists took a closer look at the predicted

theoretical value for g-2. In October 2001, theorists reported that a

mathematical error had been made in calculating the predicted value.

As a result of the revised theory estimate, the measured difference

from the Standard Model prediction reported at Brookhaven in 2001 was

less statistically significant.

 

The experimental result released in July 2002 was twice as precise as

the previous measurement and was in excellent agreement with it,

making that measurement a much more sensitive test of the Standard

Model. Since that time, much additional work has been going on to

improve scientists' understanding of and confidence in the theory

prediction for the Standard Model value. While a consensus seems to

be developing, it is still an active topic of investigation by a

large number of scientists from around the world.

 

The Standard Model theory for g-2 is composed of contributions from

three of the four forces in nature: the weak, the electric, and the

strong force. While the contributions from the weak and electric

forces can be calculated from first principles, the contribution from

the strong force cannot. This latter contribution must be determined

using experimental data. The direct determination uses data obtained

by colliding electrons and anti-electrons and measuring the particles

that are created from the strong force in the collision. The indirect

method uses data from the decay of tau particles, which are heavy

brothers of the muon and electron, along with some additional

theoretical assumptions.

 

At present the two methods do not agree very well, and in light of

this disagreement some physicists only use the direct method to

determine the theory value. The data used in both methods were

obtained at accelerators in Russia, Europe, China, and the U.S. Data

from additional experiments at accelerators in the U.S., Italy, and

Japan, when available, should help to further refine the Standard

Model theory value for g-2, giving scientists greater confidence in

the number used for comparison with the experimental result announced

today.

Molecular Imaging: Tomorrow's Stethoscope

General Electric is betting that molecular imaging is medicine's next frontier -- and a great growth opportunity. By Erick Schonfeld

 

Doctors love to scan their patients -- whether it's with X-rays, ultrasound, MRI (magnetic resonance imaging), or CT (computerized tomography). Doctors rely on imaging technologies to pinpoint what's wrong with patients before they treat or operate. As wonderful as these devices may seem, one day we will look back and think they are as crude as a stethoscope. Or, rather, the way doctors use them today will seem crude. 

 

That's because, for the most part, these machines are used to look inside our bodies at the anatomical level -- at our organs and tissues and bones. But as our understanding of the human genome and its links to disease unfolds, doctors will increasingly use these machines and others to look at what is happening inside our bodies at the molecular level -- at our cells and genes and proteins. 

 

Already, there is a machine that does this: the PET (positron-emission tomography) scanner. As Michael Phelps, the inventor of PET, once told me, "The PET scan is a way to measure the molecules of the body. It makes visible to us the living chemistry of our bodies." The way it does that is by taking a trace amount of radioactive material, inserting it into the body, and seeing what happens to it. Today, PET scans are used mostly with cancer patients to watch how much glucose a given piece of tissue is consuming (cancer cells consume a lot of glucose). But its application to other diseases is limited only by the harmless radioactive contrast agents designed to monitor a specific biological function or find a specific molecular target within the body. 

 

Indeed, it is these contrast agents that are the key to molecular medicine. Given the right agents, even older technologies such as MRI (as well as newer ones being developed) can be used to monitor molecular events. "We need new molecular probes," Phelps says. As scientists find out how genes give rise to specific diseases and cause a cascade of protein-cell interactions, contrast agents that target those interactions can be developed. Nadeem Ishaque, who heads up the molecular medicine group at GE Research, says, "It is becoming possible to look at fundamental aspects of the cell and tissue that we could not before. We can now design these contrast agents to attach to very specific events." In that way, they are just like drugs. The difference is that these agents would be seeking biomarkers of a disease -- the molecular symptoms -- rather than trying to block the disease itself. But these molecular symptoms arise early, and identifying them via molecular imaging holds the promise of personalized medicine.

Molecular imaging also holds the promise of huge profits for whoever can figure it out first. That's why General Electric (GE) is in the midst of buying Amersham, a British molecular imaging company, for $9.5 billion. It is the shift from anatomical to molecular imaging that is behind this acquisition. Amersham will be rolled into GE Medical Systems -- the market leader in medical imaging machines such as those used for X-ray, ultrasound, MRI, and PET scans -- and the whole thing will be renamed GE Healthcare Technologies. The Amersham acquisition is so important to the future of this business that Amersham's current CEO will become the new boss -- a departure from GE's usual practice of putting its own people in charge of acquisitions. Steve Bolze, the GE executive who will help oversee the integration of Amersham into GE, notes that "GE Medical Systems is not in the contrast agent business today. That is Amersham's business." 

If more contrast agents were developed that could reliably diagnose more diseases, GE would be able not only to sell more of its medical imaging machines but also to generate recurring revenue from the contrast agents. Those agents are like the profitable ink cartridges sold for computer printers that have to be constantly replenished. "The opportunity we see," Bolze says, "is [that] as you go from anatomical imaging to molecular imaging, you are going to be changing how clinical medicine is done. It will be more personalized to a specific patient's genetic profile or how they metabolize a given medicine. Instead of the see-and-treat model, we will move to a new model that is more predictive. That is when you start getting into more targeted diagnostics." And that is the opportunity that GE is eyeing.

Whether GE will be able to capitalize on that opportunity hinges on as-yet-undiscovered links between genes and diseases, the identification of biomarkers for those diseases, and the development of contrast agents (which require FDA approval) that will let doctors see those biomarkers. So this is a long-term opportunity. Today, molecular imaging represents less than 5 percent of the overall medical imaging industry. I'd say that if it ever reaches 50 percent, we'll know that personalized medicine has finally arrived.

PURDUE RESEARCH SUGGESTS 'NANOTUBES' COULD MAKE BETTER BRAIN PROBES

 

 

WEST LAFAYETTE, Ind. - Purdue University researchers have shown that 

extremely thin carbon fibers called "nanotubes" might be used to create 

brain probes and implants to study and treat neurological damage and 

disorders.

 

Probes made of silicon currently are used to study brain function and 

disease but may one day be used to apply electrical signals that 

restore damaged areas of the brain. A major drawback to these probes, 

however, is that they cause the body to produce scar tissue that 

eventually accumulates and prevents the devices from making good 

electrical contact with brain cells called neurons, said Thomas 

Webster, an assistant professor of biomedical engineering.

 

New findings showed that the nanotubes not only caused less scar tissue 

but also stimulated neurons to grow 60 percent more fingerlike 

extensions, called neurites, which are needed to regenerate brain 

activity in damaged regions, Webster said.

 

The findings are detailed in a paper appearing this month in the 

journal Nanotechnology, published by the Institute of Physics in the 

United Kingdom. The paper was written by Webster, Purdue doctoral 

students Janice L. McKenzie and Rachel L. Price, former postdoctoral 

fellow Jeremiah U. Ejiofor and visiting undergraduate student Michael 

C. Waid from the University of Nebraska.

 

The nanotubes were specially designed so that their surfaces contained 

tiny bumps measured in nanometers, or billionths of a meter. 

Conventional silicon probes do not contain the nanometer-scale surface 

features, causing the body to regard them as foreign invaders and 

surround them with scar tissue. Because the nanometer-scale features 

mimic those found on the surfaces of natural brain proteins and 

tissues, the nanotubes induce the formation of less scar tissue.

 

The scar tissue is produced by cells called astrocytes, which attach to 

the probes. The Purdue researchers discovered that about half as many 

astrocytes attach to the nanofibers compared to nanotubes that don't 

have the small features.

 

"These astrocytes can't make scar tissue unless they can adhere to the 

probe," Webster said. "Fewer astrocytes adhering to the nanotubes means 

less scar tissue will be produced."

 

The Purdue researchers pressed numerous nanofibers together to form 

discs and placed them in petri plates. Then the petri plates were 

filled with a liquid suspension of astrocytes. After one hour the 

nanotube disks were washed and a microscope was used to count how many 

of the dyed astrocytes washed out of the suspension, which enabled the 

researchers to calculate how many astrocytes stuck to the nanotubes. 

About 400 astrocytes per square centimeter adhered to the nanotubes 

containing the small surface features, compared to about 800 for 

nanotubes not containing the small surface features. The researchers 

repeated the experiment while leaving the nanotubes in the cell 

suspension for two weeks, yielding similar results.

 

When the nanotubes were placed in a suspension with neurons, the brain 

cells sprouted about five neurites, compared with the usual three 

neurites formed in suspensions with nanotubes that didn't have the 

small surface features.

 

Researchers plan to make brain probes and implants out of a mixture of 

plastics and nanotubes. The findings demonstrated that progressively 

fewer astrocytes attached to this mixture as the concentration of 

nanotubes was increased and the concentration of plastics was decreased.

 

"That means if you increase the percentage of carbon nanofibers you can 

decrease the amount of scar tissue that might form around these 

electrodes," Webster said.

 

The nanometer-scale bumps mimic features found on the surface of a 

brain protein called laminin.

 

"Neurons recognize parts of that protein and latch onto it," Webster 

said.

 

The crucifix-shaped protein then helps neurons sprout neurites, while 

suppressing the formation of scar tissue.

 

The tube-shaped molecules of carbon have unusual properties that make 

them especially promising for these and other applications. Researchers 

theorize that electrons might flow more efficiently over extremely thin 

nanotubes than they do over conventional circuits, possibly enabling 

scientists to create better brain probes as well as non-silicon-based 

transistors and more powerful, compact computers.

 

"Nano" is a prefix meaning one-billionth, so a nanometer is 

one-billionth of a meter, or roughly the length of 10 hydrogen atoms 

strung together. The nanotubes were about 100 nanometers wide, or 

roughly 1,000 times as thin as a human hair.

 

The research is funded by the National Science Foundation.

 

Webster also plans to test the effectiveness of silicon that contains 

the same sort of nanometer-scale features as the nanotubes, which could 

increase the performance of silicon probes and implants. In work with 

Spire Biomedical Inc. (Nasdaq:SPIR) in Bedford, Mass., Purdue 

researchers will analyze silicon that contains numerous pores, unlike 

conventional silicon, which has no such porous features. That research 

is funded by the National Science Foundation and the federal Small 

Business Innovation Research Program.

Nano-biotechnology: carbon nanofibers as improved neural and orthopedic  implants

 

Thomas J. Webster, Michael C. Waid, Janice L. McKenzie, Rachel L. Price 

and Jeremiah U. Ejiofor

 

Department of Biomedical Engineering, Purdue University

 

For the continuous monitoring, diagnosis, and treatment of neural 

tissue, implantable probes are required. However, sometimes such neural 

probes (usually composed of silicon) become encapsulated with 

non-conductive, undesirable glial scar tissue. Similarly for orthopedic 

implants, biomaterials (usually titanium and/or titanium alloys) often 

become encapsulated with undesirable soft fibrous, not hard bony, 

tissue. Although possessing intriguing electrical and mechanical 

properties for neural and orthopedic applications, carbon 

nanofibers/nanotubes have not been widely considered for these 

applications to date. The present work developed a carbon nanofiber 

reinforced polycarbonate urethane (PU) composite in an attempt to 

determine the possibility of using carbon nanofibers (CNs) as either 

neural or orthopedic prosthetic devices. Electrical and mechanical 

characterization studies determined that such composites have 

properties suitable for neural and orthopedic applications. More 

importantly, cell adhesion experiments revealed for the first time the 

promise these materials have to increase neural (nerve cell) and 

osteoblast (bone-forming cell) functions. In contrast, functions of 

cells that contribute to glial scar-tissue formation for neural 

prosthesis (astrocytes) and fibrous-tissue encapsulation events for 

bone implants (fibroblasts) decreased on PU composites containing 

increasing amounts of CNs. In this manner, this study provided the 

first evidence of the future that CN formulations may have towards 

interacting with neural and bone cells, which is important for the 

design of successful neural probes and orthopedic implants, 

respectively.

(Issued in Japanese: March 11, 2003)

 

  Akira TONOMURA, Fellow, Hitachi Ltd. and Group Director, The

  Institute of Physical and Chemical Research (Riken)

 

What is "the most beautiful experiment in physics"? When British

magazine Physics World asked this question, its readers chose the

double-slit experiments with single electrons, Dr. Tonomura and others

carried out. "Following our experiments, you could see big names like

Galileo and Newton in the top five," Dr. Tonomura says with a smile.

Richard Feynman once called the double-slit experiments "the heart of

quantum mechanics but impossible to perform." Dr. Tonomura succeeded

in carrying out the experiment to show, for the first time, the

essence of quantum mechanics--that single electrons can have

characteristics of both waves and particle.

PURDUE ENGINEERS DEVELOP QUICK, INEXPENSIVE METHOD TO PROTOTYPE MICROCHIPS

 

 

WEST LAFAYETTE, Ind. - Purdue University researchers have developed a

new method to quickly and inexpensively create microfluidic chips,

analytic devices with potential applications in food safety,

biosecurity, clinical diagnostics, pharmaceuticals and other industries.

 

"This development democratizes the preparation of microfluidic

biochips," said Michael Ladisch, Distinguished Professor of

Agricultural and Biological Engineering and Biomedical Engineering.

"This brings the design and manufacture of these devices within reach

of scientists in many laboratories who can now easily test their ideas

and conduct research within a typical laboratory setting."

 

Microfluidics is a branch of nanotechnology that involves manipulating

minute quantities of liquids, typically in a chip device approximately

the size of a postage stamp. The initial design and manufacture of

these chips often requires weeks of work, but the new approach

developed by Ladisch and Tom Huang, a graduate student in chemical

engineering, cuts that time to hours.

 

Microchips have traditionally been made through a lengthy and expensive

process called photolithography, which uses X-rays or ultraviolet light

to form a pattern on a glass or silicon wafer that is then etched by

washing the wafer with a variety of solvents. The key to controlling

the shape and size of the patterns on the wafer is the production of a

template, which can take weeks to develop.

 

Ladisch and his team have developed an alternative method that uses

materials easily acquired by any research laboratory, including glass

microscope slides, tweezers, thin glass fibers such as those found in

glass wall insulation, and a flexible polymer called PDMS that is

available from most scientific supply companies.

 

"What we've done is really thinking outside of the box," said Nate

Mosier, an assistant professor of agricultural and biological

engineering who also contributed to this project. "This is a radical

departure from using photolithography to make these devices."

 

The speed and simplicity of Ladisch's method gives researchers the

flexibility to experiment with the conception and construction of

microchips that can test any number of ideas.

 

"This whole device can be developed and in operation in less than two

hours," Ladisch said. "Tools like this that take a lot less time to

make and that can be manufactured in any lab are going to speed up the

rate of research."

 

Mosier said, "The capability for rapid prototyping and working out

design considerations before the manufacturing step is important to any

development, from the micro-scale on up.

 

"It's always very difficult to the make the first of anything -- the

second through the millionth are much easier."

 

The new chip assembly method involves placing a fine fiber -

approximately one-tenth the width of a human hair - on a glass slide

and covering it with a small square of the polymer PDMS. The polymer

flexes slightly over the fiber, creating a small channel on either side

of the fiber, much the same way that a sheet of plastic wrap placed on

top of a pencil would bend, making two channels running the pencil's

length.

 

A small amount of pressure applied with a finger is enough to cause the

PDMS to stick to the glass slide, Mosier said.

 

"The chemical properties of the PDMS allow it to stick to the glass

slide with enough strength to form a tight seal, which permits us to

pump liquids through the channel," Ladisch said.

 

In addition, he said, the small size of the channel - not quite the

width of a strand of hair - allows researchers to minimize their use of

experimental liquids, which may be costly or difficult to obtain.

 

In their proof-of-concept paper, published in the November issue of the

American Institute of Chemical Engineers Journal, the team showed that

coating the fibers with materials that attract different types of

molecules allowed them to separate specific proteins from a mixed

solution.

 

By manipulating the fiber's properties, scientists can identify or

separate various types of molecules, such as proteins or antibodies,

from solutions pumped through the chip.

 

Depending on the properties of the fiber, liquids placed at one end of

the channel move through the device by "wicking" along the fiber, or by

being pulled through by with a weak vacuum at the opposite end of the

channel.

 

"We can control the chemistry inside the channel to determine what

flows through, what sticks, and in that way we can separate things

out," Huang said.

 

This ability translates into numerous potential applications, such as

the ability to diagnose diseases or detect foodborne pathogens and

biological agents.

 

"These kinds of chips are essential from a security perspective," said

Bob Armstrong, senior research fellow at the National Defense

University, one of the organizations that funded this research.

 

"Microfluidic chips are becoming part of a sensor system to detect, for

example, biological or chemical agents, or pathogens in the food

supply. What is it you want to detect? Your imagination is the only

limit on how to use these devices."

 

Also collaborating on this research were Woo-Jin Chang, research

associate in electrical and computer engineering; Demir Akin, senior

research scientist in electrical and computer engineering; Rafel Gomez,

former graduate student in electrical and chemical engineering; and

Rashid Bashir, associate professor of electrical and computer

engineering and biomedical engineering.

 

The research is part of an ongoing project sponsored through the Purdue

Center for Food Safety Engineering and the Purdue Laboratory of 

Renewable Resources Engineering. Funding was provided by the

Agricultural Research Service of the U.S. Department of Agriculture,

and the Center for Technology and National Security Policy at the

National Defense University in Washington, D.C., is contributing to the

further development of this concept.

Brookhaven Scientist Develops a Safer Way to Make One Class of Superconductors

 

UPTON, NY -- A scientist at the U.S. Department of Energy's

Brookhaven National Laboratory has developed a safer, easier, and

more environmentally friendly way to create a certain experimental

type of superconductor, a material that conducts electricity with

zero resistance. This new synthesis process facilitates the study of

superconductors, which are already used in medical imaging machines

and are expected to improve the efficiency of computer chips,

electrical transmission lines, and many other real-world devices.

 

Previously, the only method used to create the superconductor, called

sodium cobalt oxyhydrate, required working with volatile and

flammable liquids. The production process also created a lot of

unwanted chemical waste. Now, Brookhaven chemist Sangmoon Park has

devised a cleaner method for synthesizing large quantities of the

superconductor using plain water. Park works in the Physics

Department's Materials Synthesis and Characterization group with his

advisor, physicist Tom Vogt.

 

The findings appeared in the November 19, 2003, issue of Physical Review B.

 

"We prepared the superconductor using an alternate route that does

not require the special precautions necessary to handle hazardous

substances," said Park. "Also, this method allows us to synthesize

large amounts of the material, which will make it easier for us to

further analyze its properties."

 

Unlike metal and metal-compound superconductors, sodium cobalt

oxyhydrate is unusual because it contains water. In fact, in early

2003 researchers discovered it was the addition of water to the

initial cobalt-oxygen compound, called cobalt oxide, that induced its

superconducting properties. Because scientists have been looking for

ways to turn other metal oxides into superconductors, this discovery,

coupled with Park¹s safer method of producing the material, may open

a door to a new avenue in superconductor research. For example,

because common metal-compound superconductors are brittle and cannot

be made into certain forms, such as pliable wire, studying

water-based superconductors may lead to materials that are less

mechanically restrictive.

 

The present material does have some drawbacks, particularly its

tendency to dry out and lose its superconductivity, making it

inconvenient to work with. But using Park's new synthesis method, the

researchers plan to look for additional, similar superconductors,

such as those that contain lithium, potassium, rubidium, or cesium in

place of sodium, to see if they can be produced as efficiently and

safely, without the need for special care. Thus, the new method will

serve as a stepping-stone for further research.

 

Experimental Method

 

To synthesize the superconductor, Park dissolved a powdery compound

made of sodium, sulfur, and oxygen into water, which caused

positively-charged sodium ions and negatively-charged molecules of a

sodium-oxygen compound, called sulfate ions, to separate from the

original compound. This solution was then mixed with another compound

composed of sodium, cobalt, and oxygen. The resulting reaction, which

generated no waste, created the superconducting material. The

structure of the material and the precise amounts of these

components, particularly the sodium and water, give the material its

superconducting properties. This was confirmed by measurements

performed by Arnold Moodenbaugh, a chemist in the Lab's Materials

Science Department.

 

At the molecular level, the superconductor consists of hexagon-shaped

layers: The cobalt oxide forms one type of layer, while the sodium

and water, together, form another. This structure is like a stack of

pancakes and waffles, with each pair of thin cobalt oxide "pancakes"

separated by a thick sodium/water "waffle." To learn about the

properties of this configuration, the material was subjected to

pressure that altered and distorted the layer structure. Because the

material loses moisture easily and must be contained in a wet

environment, the pressure was applied after first surrounding the

material with a liquid mixture of alcohol and water. The pressure

then forced alcohol or water molecules to nestle between the layers,

causing them to expand and distort. Adding these extra molecules into

the material, which increases the thickness of the sodium/water

layers, may further alter its behavior.

 

As the pressure was increased, the distortion process was studied

using a method called x-ray diffraction at the National Synchrotron

Light Source (NSLS) at Brookhaven Lab. Yongjae Lee, also of the

Materials Synthesis and Characterization Group, shined x-rays at the

material using NSLS beam line X7A and measured how the rays bent as

they passed through it. They found that, even at very low pressures,

the structure of the superconductor changed significantly. Now, Park

and his colleagues plan to investigate how these structural changes

affect the material's superconductivity.

 

"Since the discovery of sodium cobalt oxyhydrate, we've been

interested in this series of materials that have cobalt oxide layers,

and how and why they show superconducting properties, or why they

don't," Park said. "We plan to look at the rest of the series to

understand which ones are superconductors."

Invitation to attend the Albert Franks Memorial LectureTuesday, 
20 January 2004 - 18.30-20.00 hrs

The Royal Society, Carlton House Terrace, London (preceded by a complimentary drinks reception 17.30 -18.30)*

 

Hear from UK's most exciting futurologist how nanotechnology will change the way industry works,

and how our lives may change forever as a result.

 

'Nanotechnology and IT- A Glimpse of the Future'

 

Guest Speaker: Ian H. Pearson, BT Futurologist

 

"We are now on the exciting threshold of an explosion of new

technologies emanating from the convergence of information technology with

nanotechnology and biotechnology. It will become easier for anyone to

harness the full capabilities of an enriched, IT-dominated world. Artificial

intelligence (making its inevitable impact soon), combined with computing

and telecomms will be so widely and invisibly available across 'smart' urban

environments, that we will never be out of touch again, as our bodies will

be linked to a world of ubiquitous computing.

 

In this Future World, companies will have to reinvent themselves

regularly to stay in business. Mergers and acquisitions will become easier,

pushing us into a business world dominated by virtual companies.

Relationships between employees and companies will also change dramatically.

It is predicted that the information economy will then be replaced by the

care economy, with people-skills dominating over intellectual skills. This

will once again change corporate structures. Major changes across the whole

field of business are predicted, running the gamut from manufacturing to

retailing to banking and distribution."
