<DIV><FONT face=Arial size=2>Nanowires In Blood Vessels May Help Monitor,
Stimulate Neurons In The Brain. Working with platinum nanowires 100 times
thinner than a human hair--and using blood vessels as conduits to guide the
wires--a team of U.S. and Japanese researchers has demonstrated a technique that
may one day allow doctors to monitor individual brain cells and perhaps provide
new treatments for neurological diseases such as Parkinson's. Writing in the
July 5, 2005, online issue of The Journal of Nanoparticle Research, the
researchers explain it is becoming feasible to create nanowires far thinner than
even the tiniest capillary vessels. That means nanowires could, in principle, be
threaded through the circulatory system to any point in the body without
blocking the normal flow of blood or interfering with the exchange of gasses and
nutrients through the blood-vessel walls. (ScienceDaily 7/19/05) <A

<DIV><FONT face=Arial size=2>JILA study of RNA dynamics may help in drug design.
Biophysicists have developed a method for studying, in real time, a nanoscale
"docking and undocking" interaction between small pieces of ribonucleic acid
(RNA), a technique that may be broadly useful in studying structural changes in
RNA that affect its function. The research at JILA, a joint institute of the
National Institute of Standards and Technology (NIST) and University of Colorado
at Boulder, may have applications in the design of effective new drugs based on
small RNA strands. (Eurekalert 7/14/05) <A

>From catalytic converters to alternative fuels, the fight against big-city smog
has for years been fought inside combustion engines and exhaust pipes. Now,
scientists are taking the fight to the streets by developing "smart" building

<DIV><FONT face=Arial size=2>Nano-surgeons break the atomic bond. The science of
the small has moved a huge step forward following work in a subterranean
Birmingham laboratory, reports Roger Highfield. The ultimate in surgery has been
carried out in a vibration-free bunker in deepest Birmingham. Not only have
scientists working there managed to remove a single atom of matter, measuring
about a tenth of a millionth of a millimetre across, but they have achieved this
feat even though their subject was thrashing around wildly. The feat is the
ultimate in the science of the small, nanotechnology, that the practitioners
hope will one day help to remove contaminants from the environment. One can also
see it as an extreme version of precision chemistry, a far cry from what usually
happens in a laboratory.</FONT></DIV>

<DIV><FONT face=Arial size=2>The first nanoparticle drug delivery system reaches
the market. On 8th February 2005, the first nanoparticulate drug delivery
product, Abraxane for the treatment of breast cancer was launched by Abraxis
Oncology, a division of American Pharmaceutical Partners, Inc. The initial
announcement in late 2004 saw the company’s share prices rise by 50% and
required the Food and Drug Administration (FDA) to create a new class of
therapeutic products. Operating at scales of billionths of a metre, nanoparticle
drug delivery systems involve binding a therapeutic compound to a nanoparticle,
or encasing it within a nanoshell. Common materials in development include gold
or silicon nanoparticles, with the Abraxane system using a nanoparticle shell
constructed from albumin. A key advantage of nanoshells is that they can be
targeted to specific cell populations through conjugation with a monoclonal
antibody. </FONT></DIV>

of Millcreek, Erie County, formerly of South Strabane, is seeking five patents
for his radio-wave cancer treatment that could offer an alternative to surgery

inventions on rats in May, and University of Texas M.D. Anderson Cancer Center
in Houston, the nation's top-ranked cancer center, plans to begin testing it on
rabbits and pigs. Now Richard E. Smalley, winner of the 1996 Nobel Prize in
chemistry for creating carbon-based molecules known as buckyballs and nanotubes,
will collaborate with M.D. Anderson on Kanzius' inventions. Smalley, founder of
the Rice University Carbon Nanotechnology Laboratory in Houston, has the same

<DIV><FONT face=Arial size=2>The market for the instruments and tools needed to
work on the nanoscale faces substantial challenges in the future, experts told
UPI's Nano World. Atomic-force microscopes, or AFMs, and other tools that
experiment on carbon nanotubes and other areas outside the semiconductor
industry "are the things that make nanotechnology possible to begin with," said
Nathan Tinker, co-founder and executive vice president of the NanoBusiness
Alliance in New York City."They represent the state of the art, and the ability
for nanotechnology to drive forward institutionally across industrial
sectors."Nanotech analysis group Lux Research, also in New York, has estimated
the global impact of nanotech-enabled goods at $2.6 trillion by 2015...Still,
the costs for ramping up the mostly research-oriented tools used to work on the
nanoscale to large-scale production processes are going to be substantial,
Tinker said.Moreover, this ramping up is only a fraction of the challenge ahead.
"The big problem seems to me in getting these machines to the point of
reliability needed at an industrial scale," he said." (PhysOrg 7/22/05) <A
