Cancer fight could advance via thin film. Chemotherapy drugs are
intended to kill the fast-growing cancer cells that populate tumors,
but the poison kills a lot of innocent bystander cells as well.
Nanotech researchers who seek ways to send chemokillers where they're
needed while avoiding healthy tissue had some good news last week in
the form of a film so thin as to be virtually invisible. (Chicago
Tribune 1.28.08)

Scientists Make 'Perfect' Nanowires. Scientists have created silicon
nanowires that are perfectat least atomically. Down at the single-atom
level, the identical wires have no bumps, bends, or other
imperfections. They are perfectly crystalline, even more so than bulk
silicon. The full array of nanowires is also highly parallel, and each
wire is an excellent metallic conductor. (Physorg 1.23.08)

Vision of the future: Researchers build bionic eye. Nanotech could let
travelers check Net, e-mail or play games on floating display
screen...University researchers reported that they have used
nanotechnology manufacturing techniques to combine a flexible,
biologically safe contact lens with an imprinted electronic circuit
and lights. Perfecting virtual displays could mean that traveling
executives could surf the Net or check their e-mail on a floating
virtual display screen that only they could see. It also would mean
that drivers could see their speed projected onto the windshield, or
gamers could become far more immersed in their virtual worlds.

Nanowires hold promise for more affordable solar cells...The
Department of Engineering Physics at McMaster University, Cleanfield
Energy and the Ontario Centres of Excellence (OCE) have formed a
partnership to pursue the commercialization of nanowire technology in
the production of solar cells. The particular type of nanowire
technology developed at McMaster is able to trap more sunlight and
convert it to electricity more efficiently than traditional solar
cells. (Nanotechwire 1.25.08)

DNA 'fabricator' constructs walking DNA. The goal of being able to
program biochemical reactions as precisely and easily as computers
crunch numbers and process words has moved a giant step closer. A
group at the California Institute of Technology, led by biomolecular
engineer Niles Pierce, has created a DNA-based fabricator. This is a
system that allows the team to specify a piece of DNA with a desired
shape and function, and then execute a molecular program to assemble
it in a test tube. As an example, they used their system to construct
a piece of DNA that walks along another strip of DNA. (Newscientist

Fine print: New technique allows fast printing of microscopic
electronics. A new technique for printing extraordinarily thin lines
quickly over wide areas could lead to larger, less expensive and more
versatile electronic displays as well new medical devices, sensors and
other technologies. Solving a fundamental and long-standing quandary,
chemical engineers at Princeton developed a method for shooting stable
jets of electrically charged liquids from a wide nozzle. The
technique, which produced lines just 100 nanometers wide (about one
ten-thousandth of a millimeter), offers at least 10 times better
resolution than ink-jet printing and far more speed and ease than
conventional nanotechnology. (Eurekalert 1.24.08)

Controlling Cell Behavior with Magnets. Nanoparticles allow
researchers to initiate biochemical events at will. For the first
time, researchers have demonstrated a means of controlling cell
functions with a physical, rather than chemical, signal. Using a
magnetic field to pull together tiny beads targeted to particular cell
receptors, Harvard researchers made cells take up calcium, and then
stop, then take it up again. Their work is the first to prove that
such a level of control over cells is possible. If the approach can be
used with many cell types and cell functions, it could lead to a
totally new class of therapies that rely on cells themselves to make
and release drugs. (Technologyreview 1.18.08)

Nanotechnology Innovation May Revolutionize Gene Detection In A Single
Cell. Scientists at Arizona State University's Biodesign Institute
have developed the world's first gene detection platform made up
entirely from self-assembled DNA nanostructures. The results,
appearing in the January 11 issue of the journal Science, could have
broad implications for gene chip technology and may also revolutionize
the way in which gene expression is analyzed in a single cell.

Scientists discover new method of observing interactions in nanoscale
systems. Scientists have used new optical technologies to observe
interactions in nanoscale systems that Heisenbergs uncertainty
principle usually would prohibit, according to a study published Jan.

Artificial Viral Shells Could Be Useful Nano-Containers. Researchers
at the Technion-Israel Institute of Technology and The Scripps
Research Institute in California are designing an artificial viral
shell as a valuable nano-container for pinpoint drug delivery,
molecular computing components, and a host of other applications.

Was Tipu's sword made using nanotechnology? Indians had the know-how
for nanotechnology, one of the latest branches in science, from 18th
century only, a Nobel Laureate in Chemistry said on Monday. Robert F
Curl, the Nobel Laureate, said right from the 18th Century, Indians
were using nanotechnology, and the sword of Tipu Sultan is one
example. However, he refused to comment as to whether they were using
it knowingly or unknowingly. Similarly, there are examples of the use
of nanotechnology in preparing glass in Rome, he said speaking to
media persons on the sidelines of a lecture. (The Hindu 12.31.07)

...Nanotechnology researchers have now been able to demonstrate that
semiconductor nanowires can be designed to achieve extremely large
enhancements in thermoelectric efficiency. Bulk silicon is a very
inefficient thermoelectric material. It conducts heat so well that is
is difficult to produce a temperature difference big enough to
generate any useful voltage at all. (Nanowerk 1.16.08)

Surprise: silicon nanotechnology turns heat into electricity. Two
teams of US scientists have demonstrated silicon-based thermoelectric
materials that could convert waste heat back into electricity -
potentially giving a boost to the efficiency of everything from power
stations to refrigerators (Nanodot 1.17.08)

Dark, dark nanotechnology. An ideal black object absorbs all of the
colors of light and reflects none of them. Researchers at Rice
University have demonstrated a new concept based on a low-density
nanotube array material that can be engineered to dramatically change
an objects index of refraction and nanoscale roughness, hence, its
optical reflection.
An article in the Houston Chronicle puts it like this: "A scientist at
Rice University has created the darkest material known to man, a
carpet of carbon nanotubes that reflects only 0.045 percent of all
light shined upon it. That's four times darker than the previously
darkest known substance, and more than 100 times darker than the paint
on a black Corvette." (Nanowerk 1.15.08)

Nanotechnology improves the prospect of better treatment for brain
disorders...In a recent review in the Journal of Peptide Science, Dr.
Ernest Giralt from the Institute for Research in Biomedicine in
Barcelona, Spain, together with Dr. Meritxell Teixidó from his group,
summarized literature reports on the use of peptides and
nanotechnology for the treatment and diagnosis of brain disorders, and
comparing these approaches to other methods..."Over the past few
decades, pharmaceutical technology has lead to the emergence of
different nanosystems or nanoplatforms tailored to deliver drugs to
the brain, including polymeric nanoparticles, liposomes, and solid
lipid nanoparticles" Giralt tells Nanowerk. (Nanomednet 1.7.08)

Scientists invent nanotechnology device for disease biomarker
discovery. Scientists at George Mason Universitys Center for Applied
Proteomics and Molecular Medicine have invented an innovative
nanotechnology tool that may lead to a dramatic improvement in
treatment results for patients diagnosed with cancer or other
diseases. The novel diagnostic tool is uniquely suited for the
discovery of new protein biomarkers in the blood that provide
sensitive and specific disease detection at the earliest stage when
treatment is most effective. (Nanovip 1.14.08)
