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. (Iowa State

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 university's 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 JILA-a tiny gold beam whose 40 million vibrations per
second are measured by hopping electrons-offers 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.

A new nano-insulin delivery pump for worry-free treatment for diabetics...In
what may be a sizeable breakthrough in medical technology (and quite a
relief for diabetics), medical device company Debiotech and
Switzerland-based STMicroelectronics have entered into a strategic
cooperation agreement to manufacture and deliver the award-winning
miniaturised insulin-delivery pump. (Business Standard 5.1.07)

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.

Magnetic tweezers unravel cellular mechanics. By injecting tiny magnetic
beads into a living cell and manipulating them with a magnetic 'tweezer',
scientists of the University of Twente, The Netherlands, succeed in getting
to know more about the mechanics of the cell nucleus. (physorg 5.14.07)

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

Inexpensive 'nanoglue' can bond nearly anything together. Researchers at
Rensselaer Polytechnic Institute have developed a new method to bond
materials that don't normally stick together. The team's 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 adhesive's 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

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: 10.1021/es061953l).(NewScientist 5.5.07)

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

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

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 5.10.07)

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 5.18.07)

I think this is great & I hope it works. But hasn't this been the main
goal of cancer research for the last 50 years, along with the tens of
billions of dollars spent on research?
