How to Build a Biobot. Synthetic-biology researchers are creating a tool kit
to build biobots, autonomous, special-purpose nanorobots the size of cells,
with applications in medicine, national security, environmental protection,
and many other fields. Too simple to replicate, biobots will be put together
like Legos from a catalogue of biological and artificial parts.

Nanoscale parts get binding aid. Nanoscale particles that are easy to
manufacture piecemeal - but hard to assemble - may benefit from a new
"sticky patch" technology that researchers at the University of Michigan say
enables nanoscale self-assembly. "By mimicking biological assembly, we are
exploring ways to nanoengineer materials that are self-assembling,
self-sensing, self-healing and self-regulating," said Sharon Glotzer, an
associate professor of chemical engineering on the Ann Arbor campus.

Spotlight on Nanotubes. Think of it as track lighting on the smallest
possible scale. Physicists recently discovered that a tiny tube-like
molecule of carbon can produce light when electricity passes through it.
Now, the same team has captured images of the precise spot from which the
light shines, and by varying the applied voltages, the researchers have even
moved the spot back and forth along the 3-nanometer-wide molecule. Described
in the 13 August PRL, the effect provides a new tool for studying the inner
workings of nanotubes, which might someday serve as the building blocks for
molecular electronic circuits. (PRL 8/19/04)

Tiny Writing: Researchers Develop Improved Method to Produce Nanometer-scale
Patterns. Researchers from the Georgia Institute of Technology and the Naval
Research Laboratory (NRL) have developed an improved method for directly
writing nanometer-scale patterns onto a variety of surfaces. The new writing
method, dubbed "thermal dip pen nanolithography," represents an important
extension for dip pen nanolithography (DPN), an increasingly popular
technique that uses atomic force microscopy (AFM) probes as pens to produce
nanometer-scale patterns. (Georgia Tech 8/30/04)

A Push-Pull Approach to Proteins. Researchers learn the biophysical
properties of bacterial condensin. By stretching a poorly understood protein
like a rubber band, a team of Berkeley Lab and University of California at
Berkeley scientists is learning how the protein and its cousins perform some
of life's most fundamental tasks. Their work, published in the journal
Science, is the first look at the biophysical properties of a condensin.

Nanotubes may have no 'temperature'. Could quantum effects plague miniature
devices? Physicists have made a bizarre discovery: the concept of
temperature is meaningless in some tiny objects. Although the concept of
temperature is known to break down on the scale of individual atoms,
research now suggests that it may also fail to apply in rather larger
entities, such as carbon nanotubes. (Nature 8/17/04)

(UK) Nanotechnology projects win 15 million funding from DTI. The
Department of Trade and Industry has given a major boost to Nanotechnology
projects throughout the UK. Twenty five projects are to receive 15 million
worth of funding for projects ranging from anti-corrosion coatings and
electronics to water purification and printing. This new investment will
provide up to a maximum of 50% of each project's total value. A further 3
million will be given to INEX, a microsystems and nanotechnology facility
for industry based at Newcastle. These grants are the first to be allocated
from the Government's 90 million micro and nanotechnology manufacturing
initiative in support of both nanotechnology applied research programmes and
for the creation of new nanotechnology facilities across the country.
Further grants will be made available over the next five years to complete
the initiative.

RNA shapes up for "nano-scaffolding". Researchers at Purdue University, US,
have made a variety of shapes from molecules of packaging ribonucleic acid
(pRNA). The forms included twins, tetramers, triangles, rods and
three-dimensional arrays. "Our work shows that we can control the
construction of three-dimensional arrays made from RNA blocks of different
shapes and sizes," said Peixuan Guo of Purdue. "With further research, RNA
could form the superstructures for tomorrow's nanomachines." (Nanotechweb

Scientists Reinvent DNA As Template To Produce Organic Molecules. By
piggybacking small organic molecules onto short strands of DNA, chemists at
Harvard University have developed an innovative new method of using DNA as a
blueprint not for proteins but for collections of complex synthetic
molecules. The researchers will report on the prolific technique, dubbed
"DNA-templated library synthesis," this week on the web site of the journal
Science. (Bio.com 8/20/04)

Nanotube Dynamos. Two scientists in India have produced a tiny voltage in a
small electrical circuit by blowing gas across a mat of carbon nanotubes and
doped semiconductors. This result arises from two physical effects. First,
in the Bernoulli effect, gas rushing past a surface produces pressure
differences along streamlines, which in turn can produce a temperature
gradient along a material sample. (Physics News Update 8/19/04)

Holographix Finds Replication Niche in Nano Industry. Call it the art of
making cheap knockoffs, at the nanoscale. Holographix LLC, a 10-person
startup in suburban Boston, knows it has neither the resources nor the
expertise to fabricate nanoscale components. So the team has put its efforts
in another valuable niche of nanoscale manufacturing: making inexpensive
replicas of components that others have fabricated already. (8/23/04)

Smooth operators: New fabrics fight off wrinkles and stains. We may soon be
listening to music emitted by the fabric of our clothing or watching our
shirts change color as we heat up. But the hottest thing in fabric for the
moment is only a little less remarkable, able to fight off dirt and wrinkles
like something out of Superman's closet. That's the view from Eva Snopek,
fashion design instructor at the Illinois Institute of Art in Chicago.
"There is a lot of new technology out there," she said, citing
nanotechnology as the superstar of the day. And our testing backed her up.

Grad's Breakthrough Artificial Pancreas May Help Diabetics. Even though her
colleagues told her it was impossible to create an artificial pancreas that
could alleviate diabetes, and that she would never finish it in time to
graduate from UC Berkeley, Tejal Desai finished what she set out to
do...Desai, 31, built an implantable device-containing live pancreas
cells-that could be used in place of daily insulin injections for diabetics
to control their blood sugar levels...This combination of biology and
nanotechnology was unknown when Desai began her research, but bioengineering
breakthroughs such as her own are making it a quickly growing field.

Little particles make cars, profits shine. Keith Matthews knows his car wax.
A car detailer at International Motor Car Co., 2111 Dana Ave., he puts a
shine on two or three vehicles a day for the luxury-car dealership. "Nanowax
is the best thing I've used, and I've been doing this for 15 years,'' he
said. Eagle One Nanowax, produced by Ashland Inc.'s Lexington-based
Valvoline unit, is easier to apply, leaves less residue and does a better
job of handling swirls and defects in car finishes, he says. (Enquirer

Chemical Sensors Made from Nanomaterials. New types of chemical sensors for
environmental monitoring, food safety or security applications could be
based on nanotechnology, according to Frank Osterloh, an assistant professor
of chemistry at UC Davis. "Nanomaterials are very well suited for chemical
sensor applications, because their physical properties often vary
considerably in response to changes of the chemical environment," Osterloh
said.

Trapped Single Atom Presages New Technology. Once thought impossible to
catch, scientists have now snared a single atom. A report from the
Department of Energys Oak Ridge National Laboratory (ORNL) in Tennessee
says that collaborating Indian-American researchers have accomplished the
feat, which could lead to a whole new technology. ORNL scientists Thomas
Thundat and Adosh Mehta have collaborated with Ramesh Bhargava of
Nanocrystals Technology in Briarcliff, N.Y., to cage single atoms in
nanocrystals not much larger than the atoms themselves. Previous attempts to
catch atoms have been difficult because of the unpredictable nature of
atoms, as dictated by the rules of quantum mechanics. (Indolink 8/20/04)
