<DIV><FONT face=Arial size=2>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)<BR><A

have created silicon nanowires that are perfect—at 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) <A

<DIV><FONT face=Arial size=2>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 1.16.08)<BR><A

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

<DIV><FONT face=Arial size=2>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)<BR><A
