Nanotechnology is showing promise in treating spinal cord injuries and
could conceivably reverse paralysis, according to a report on the
future of the emerging technology in medicine. The report, released at
a Washington forum this week, said nanotechnology -- or the use of
materials on the scale of atoms and molecules -- may also help cure
other ailments believed to be intractable by repairing damaged organs
or tissue. This suggests damage from heart attacks or strokes, bone or
tooth loss or ailments such as diabetes and Parkinson's disease could
be treated with nanotechnology, researchers said.

100% Biodegradable NANOIL Ready For Automobiles. Nano Chemical Systems
Holdings, Inc., announced recently their latest entry into the
multi-billion dollar performance chemical category, NANOIL, a
"nano-enhanced" GREEN motor oil. Unlike today's fossil and synthetic
oils, NANOIL is non-toxic and bio-degradable, thus eliminating the
current disposal issues with present commercially available
lubricants. Nanochem will produce NANOIL utilizing its nano-technology
patent applications and inventions that directly address bio-fuel
production for a nano-enhanced line of "green" bio-lubricants. Initial
results indicate that these bio-lubricants can perform as well as
today's fossil and synthetic oils. (Chemical Online 4.27.07)

Finding by Rice University chemists could aid development of new
nanodevices. Gold nanorods assemble themselves into rings. Rice
University chemists have discovered that tiny building blocks known as
gold nanorods spontaneously assemble themselves into ring-like
superstructures. This finding, which will be published as the inside
cover article of the March 19 international edition of the chemistry
journal Angewandte Chemie, could potentially lead to the development
of novel nanodevices like highly sensitive optical sensors,
superlenses, and even invisible objects for use in the military.

Plenty of room for MRIs at a nano scale... a research team now
reports. Combining an MRI with the precision of atomic-force
microscopes, a team led by Dan Rugar of the IBM Research Division in
San Jose, Calif., unveiled MRI images 60,000 times smaller than
anything imaged by MRI previously, down to 90 nanometer resolution
about 10 times bigger than your typical molecule and right in the
range of the integrated circuits doing all the calculations behind
your computer screen. The result, the team writes in the current
Nature Nanotechnology journal, "demonstrates the feasibility of
pushing MRI into the nanoscale regime." (USA Today 5.1.07)

Iowa State scientists demonstrate first use of nanotechnology to enter
plant cells. A team of Iowa State University plant scientists and
materials chemists have successfully used nanotechnology to penetrate
plant cell walls and simultaneously deliver a gene and a chemical that
triggers its expression with controlled precision. Their breakthrough
brings nanotechnology to plant biology and agricultural biotechnology,
creating a powerful new tool for targeted delivery into plant cells.

Super small nanoelectrodes can probe microscale environments.
Investigating the composition and behavior of microscale environments,
including those within living cells, could become easier and more
precise with nanoelectrodes being developed at the University of
Illinois. The individual nanotube-based probes can be used for
electrochemical and biochemical sensing, said Min-Feng Yu, a U. of I.
professor of mechanical science and engineering, and a researcher at
the universitys Beckman Institute. The position of the nanoelectrodes
can be controlled very accurately.

An Australian biotechnology firm said on Thursday it had developed a
means of delivering anti-cancer drugs directly to cancer cells, which
aims to avoid the debilitating toxicity associated with chemotherapy.
The method uses nanotechnology, which involves molecules far smaller
than a human cell. Direct targeting of chemotherapy drugs would allow
dosages thousands of times lower than that in conventional
chemotherapy and be more easily tolerated by patients, said the firm.
Writing in the May issue of U.S.-based Cancer Cell journal, the
biotech firm EnGeneIC said it had developed nano-cells containing
chemotherapy drugs. (Yahoo 5.10.07)

New JILA apparatus measures fast nanoscale motions. A new nanoscale
apparatus developed at JILAa tiny gold beam whose 40 million
vibrations per second are measured by hopping electronsoffers the
potential for a 500-fold increase in the speed of scanning tunneling
microscopes (STM), perhaps paving the way for scientists to watch
atoms vibrate in high definition in real time. The new device measures
the wiggling of the beam, or, more precisely, the space between it and
an electrically conducting point just a single atom wide, based on the
speed of electrons tunneling across the gap. The work is the first use
of an atomic point contact, the business end of an STM, to sense a
nanomechanical device oscillating at its resonant frequency, where it
naturally vibrates like a tuning fork. (EurekAlert 3.16.07)

Paralyzed Mice Walk Again. Scientists Use Nanotechnology to Mend
Broken Spinal Cords. Samuel Stupp has a bunch of mice that used to
drag their hind legs behind them when they crawled around his Illinois
lab, but they have miraculously regained at least partial use of their
rear legs. Astonishingly, their severed spinal cords have been
repaired, at least partly, without surgery or drugs. All it took was a
simple injection of a liquid containing tiny molecular structures
developed by Stupp and his colleagues at Northwestern University. Six
weeks later, the mice were able to walk again. They don't have their
former agility, but their injuries should have left them paralyzed for
life... Stupp's team concentrates on combining the incredibly small
world of nanotechnology with biology, creating molecules that
self-assemble into large molecular structures that can literally "hug"
around cells in the human body. (ABC News 5.1.07)

A Single-Photon Server with Just One Atom. Physicists at Max Planck
Institute of Quantum Optics have succeeded in turning a Rubidium atom
into a single-photon server. The high quality of the single photons
and their ready availability are important for future quantum
information processing experiments with single photons. In the
relatively new field of quantum information processing the goal is to
make use of quantum mechanics to compute certain tasks much more
efficiently than with a classical computer. (Max Planck Society

Student Creates Garment With Bacteria-trapping Nanofibers. Fashion
designers and fiber scientists at Cornell have taken "functional
clothing" to a whole new level. They have designed a garment that can
prevent colds and flu and never needs washing, and another that
destroys harmful gases and protects the wearer from smog and air
pollution. The two-toned gold dress and metallic denim jacket,
featured at the April 21 Cornell Design League fashion show, contain
cotton fabrics coated with nanoparticles that give them functional
qualities never before seen in the fashion world. (Science Daily

Inexpensive 'nanoglue' can bond nearly anything together. Researchers
at Rensselaer Polytechnic Institute have developed a new method to
bond materials that dont normally stick together. The teams adhesive,
which is based on self-assembling nanoscale chains, could impact
everything from next-generation computer chip manufacturing to energy
production. Less than a nanometer or one billionth of a meter thick,
the nanoglue is inexpensive to make and can withstand temperatures far
higher than what was previously envisioned. In fact, the adhesives
molecular bonds strengthen when exposed to heat. (EurekAlert 4.16.07)

Demand for nanotech-based medicine grows. U.S. demand for
nanotechnology medical products will increase over 17 percent per year
to $53 billion in 2011, says The Freedonia Group, Inc., a
Cleveland-based industry research firm. Afterwards, the increasing
flow of new nanomedicines, nanodiagnostics, and nanotech-based medical
supplies and devices into the US market will boost demand to more than
$110 billion in 2016. The firm reports these and other findings in its
new study, Nanotechnology in Healthcare. (SmallTimes 3.19.07)

Lighting the nanoworld with nanolamps. An interdisciplinary team of
researchers at Cornell University (CU) has built 'nanolamps.' These
extremely small light bulbs are made of light-emitting nanofibers
about the size of a virus or the tiniest of bacteria. Using a
technique called electrospinning, the researchers spun the fibers from
a metallic element, the ruthenium, and a polymer. These nanofibers
"are so small that they are less than the wavelength of the light they
emit." Apparently, these nanofibers are easy to produce. But before
they can be integrated into our increasingly smaller electronic
devices, there still is a need to know how long these nanolamps can
last.

Nanoparticles 'safe for soil bugs'. Ronald Turco at Purdue University
in West Lafayette, Indiana, and his colleagues have found that
fullerenes, nanoscale carbon spheres, do not harm microbes when
released into the soil. Their study is the first of its kind to focus
on soil microbes, which play a key role in recycling nutrients used by
plants (Environmental Science & Technology, DOI:

Nanorockets - the ultimate baby boosters? Brian Gilchrists. design
for a rocket ship sounds like a bad joke. For a start, its engine is
about the size of a single bacterium. And for thrust it relies on the
equivalent of chucking microscopic beer cans out of the spacecraft's
rear window. Gilchrist, an electrical engineer at the University of
Michigan, Ann Arbor, is not joking though. He proposes to harness the
latest nanotechnology to create an engine that will make its way
across the solar system by firing out minute metal particles like so
much nano-sized grapeshot. (New Scientist 3.24.07)

Growing Nerve Cells in 3-D Dramatically Affects Gene Expression. Nerve
cells grown in three-dimensional environments deploy hundreds of
different genes compared with cells grown in standard two-dimensional
petri dishes, according to a new Brown University study. The research,
spearheaded by bioengineer Diane Hoffman-Kim, adds to a growing body
of evidence that lab culture techniques dramatically affect the way
these cells behave. (Brown 5.15.07)

The longest carbon nanotubes you've ever seen. Using techniques that
could revolutionize manufacturing for certain materials, researchers
have grown carbon nanotubes that are the longest in the world. While
still slightly less than 2 centimeters long, each nanotube is 900,000
times longer than its diameter. The fibers--which have the potential
to be longer, stronger and better conductors of electricity than
copper and many other materials--could ultimately find use in smart
fabrics, sensors and a host of other applications. To grow the aligned
bundles of tiny tubes, the researchers combined advantages of chemical
vapor deposition (CVD), a technique for creating thin coatings that is
especially common in the semiconductor industry, with a novel
substrate and catalyst onto which the carbon attaches. (EurkAlert

Nanoscale pasta: Toward nanoscale electronics. Pasta tastes like pasta
with or without a spiral. But when you jump to the nanoscale,
everything changes: carbon nanotubes and nanofibers that look like
nanoscale spiral pasta have completely different electronic properties
than their non-spiraling cousins. Engineers at UC San Diego, and
Clemson University are studying these differences in the hopes of
creating new kinds of components for nanoscale electronics. (physorg
