<DIV><FONT face=Arial size=2>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. <BR>(ScienceBeat 8/27/04) <A

<DIV><FONT face=Arial size=2>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.

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

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)<BR><A

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

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
