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)

UCLA chemists create nano valve. UCLA chemists have created the first nano valve
that can be opened and closed at will to trap and release molecules. The
discovery, federally funded by the National Science Foundation, will be
published July 19 in the Proceedings of the National Academy of Sciences. "This
paper demonstrates unequivocally that the machine works," said Jeffrey I. Zink,
a UCLA professor of chemistry and biochemistry, a member of the California
NanoSystems Institute at UCLA, and a member of the research team. "With the nano
valve, we can trap and release molecules on demand. We are able to control
molecules at the nano scale. (Medicalnewstoday 7/17/05)

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.

Scientists making self-cleaning building products. 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 materials designed to clean
the air with a little help from the elements. Using technology already available
for self-cleaning windows and bathroom tiles, scientists hope to paint up
cities with materials that dissolve and wash away pollutants when exposed to sun
and rain. (Clarionledger 7/23/05)

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.

Molecular Logic Gate Operates In Nanospace. Computation molecule is confined
within a detergent micelle. Chemists in Northern Ireland and Japan have designed
a fluorescent molecule that carries out a logical computation in the nanospace
of a membrane (J. Am. Chem. Soc. 2005, 127, 8920). The system operates as a
two-input AND logic gate, in which two conditions must both be satisfied to
produce an output. (C&Enews 6/20/05)

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.

Nano-Tex makes nasty stains disappear like magic. Matt Hurwitz flies around the
country spilling things on himself. That cheap red wine tucked into his
oversized suitcase isn't for drinking. Neither is the grape juice. Point a
camera at this guy and he cheerfully sloshes red wine over shirt, tie and pants.
Whoa! What kind of a magic trip is this? Hurwitz is a man on a mission with a
message. He's out to tell the world about fabrics treated with Nano-Tex, a
nanotechnology treatment originated in California to "bathe" fabrics with nano
molecules ("1 million times smaller than a grain of sand," he explains).

Nobel Prize winner to join cancer research team. A Nobel laureate who has
leukemia has joined an all-star team of researchers testing a Washington County
native's novel cancer treatment. John Kanzius, 61, 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 and chemotherapy.
University of Pittsburgh Medical Center began testing his 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 B-cell
leukemia afflicting Kanzius. (PostGazette 7/22/05)

New Method Purifies Nanoparticles. To meet the stringent purity requirements of
the U.S. Food and Drug Administration, pharmaceutical manufacturers will need
robust, economical methods for cleaning up and recovering nanoparticles. While
many methods exist for purifying small amounts of nanoparticles, such techniques
are often difficult or uneconomical to use on even the modest scale needed to
produce an approved pharmaceutical or imaging agent. (National Cancer Institute

NanoBio Corporation, announced today that it has successfully completed its
Phase 2 study of NB-001 in patients with herpes labialis (cold sores) and is
moving ahead with plans to conduct Phase 3 clinical trials next year. NB-001 is
a topical emulsion comprised of nanometer-size water/oil droplets coated with a
surfactant that has demonstrated potent anti-viral, anti-bacterial and
anti-fungal activity in previous studies. These uniformly small antimicrobial
particles are designed to accelerate the healing of skin ulcers by killing the
herpes viruses at the lesion site. (Nanotechnology Now 7/22/05)

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)

'Tall' crystals from tiny templates. Ames Lab Researchers Modify Old Technique
to Make 3-D Multilayered Structures. Achieving a first in the world of novel
optical materials, researchers at the U. S. Department of Energy's Ames
Laboratory are making 3-D photonic band gap crystals four millimeters square
(approximately one-eighth of an inch square) and 12 layers high without benefit
of a "clean room" environment or the multimillion dollar equipment traditionally
required to create such structures. The fundamental research, supported by the
Basic Energy Sciences Office of the DOE's Office of Science, holds potential for
significantly reducing the costs associated with fabricating PBG crystals,
devices that make it possible to route, manipulate and modify the properties of
light. (AmesLab 7/21/05)

Nano-imprint makes its mark. Nano-imprint lithography (NIL) could become more
than just a novel process - it could replace conventional lithography
completely. Although most of the semiconductor industry is still learning to
build chips with circuits as narrow as 90 nanometres, Hewlett-Packard researcher
Stan Williams is using a novel process called nano-imprint lithography (NIL) to
make experimental memory chips with tiny electrical pathways less than half
that size. "We're now using imprint lithography to routinely make real,
operating circuits with a half-pitch [width] of 30 nanometres," says Williams, a
senior fellow and director of quantum science research at HP Labs.
