President's advisers to consider export controls on nanotech. A panel that advises President Bush on export issues will explore whether nanotechnology needs regulating. The committee, which will be assembled early this year, is expected to review other nations' nanotechnology capabilities, their competitiveness and nanotechnology's impact on national security. Lawyers who specialize in export law recommend nanotechnology companies follow developments to ensure they comply if regulations eventually are put in place. The scope could range from restrictions on international trade to rules on staffing foreign nationals. (Smalltimes 2/3/05)

A highly sensitive new test could lead to a different way to diagnose people with Alzheimer’s disease, possibly helping find the illness in its early stages when there might be time for treatment...Test measures proteins in spinal fluid. Many companies have experimental therapies, he said, “But those therapeutics aren’t very good if you can’t definitively diagnose and follow a disease,” explained Mirkin, a lead researcher — along with William L. Klein — on a team that developed the new test, which can detect small amounts of proteins in spinal fluid. The team’s findings are reported in Tuesday’s issue of Proceedings of the National Academy of Science. (MSNBC 2/1/05) http://www.msnbc.msn.com/id/6890966
Controlling guests in nanocapsules. "A detailed understanding of the interplay and relative orientations of the constituent guest molecules has, until now, been restricted to a few instances of limited complexity," note chemistry professor Jerry L. Atwood and coworkers at the University of Missouri, Columbia, in a recent paper [Angew. Chem. Int. Ed., 43,5263 (2004)]. The paper describes two important advances relating to nanocapsules with interior volumes in the 1,200?1,500-?3 range, according to Atwood. "First, we show that it is possible to order the guests on the interior of our large free-standing capsules," he says. "Second, and most remarkably, we show that these large capsules communicate with each other, at least in the solid state and probably in solution, by the formation of intercapsule hydrogen bonds. This communication in turn leads to a completely different ordering of the guests within the capsules."

A company called Kereos is developing a pair of nanotechnologies to identify tumors that measure just 1 mm in diameter, then kill them with a tiny but precise amount of a chemotherapy drug. The technologies, if approved by the Food and Drug Administration, would not only find cancers in their earliest stages before they can do damage or spread, but also deliver a small amount of a drug targeted directly at tumors, which would cause little or no side effects. The technologies are in the early stages of development. The diagnostic tool will enter human trials in 2005, and the therapeutic tool should follow six months behind, according to company officials. "What's really neat about this pair is they both track the same biomarker," said Al Beardsley, president and CEO of Kereos in St. Louis. "We're using it as a signpost to say, 'Hey there's a tumor over there.' And then as a therapeutic target." Wired 6/22/04. Chemists make molecular interlocked rings. UCLA chemists have devised

head of a company that's making it happen. "I think nanomedicine

what might be possible," Texan millionaire Jim Von Her said in Wellington,
New Zealand, while attending a nanotechnology conference. "We can't
build any of the devices he has designed yet because we don't have atomic
precision. But in 20 years we are going to be able to make little devices

1/17/03. Nanotech oversight bill reintroduced. Legislation establishing a government advisory board to oversee a U.S. nanotechnology initiative was reintroduced this week in the House of Representatives. The bill, sponsored by Rep. Mike Honda, D-Calif., calls for industry and university experts to serve on an advisory panel that would advise the Bush administration and Congress on research investments and goals for the U.S. National Nanotechnology Initiative. Similar legislation was introduced in October by Honda, a member of the House Science Committee. The bill calls for the formation of an advisory panel that would develop short-, medium- and long-range objectives for nanotechnology development over the next decade and beyond.

Researchers have shown how tiny wires and metallic spheres might be arranged in various shapes to form "nanoantennas" that dramatically increase the precision of medical diagnostic imaging and devices that detect chemical and biological warfare agents. Engineers from Purdue University have demonstrated through mathematical simulations that nanometer-scale antennas with certain geometric shapes should be able to make possible new sensors capable of detecting a single molecule of a chemical or biological agent. Such an innovation could result in detectors that are, in some cases, millions of times more sensitive than current technology. Purdue News 8/21/02 Stamps and glue make circuits. Rubber stamps, ink and glue -- tools of choice for grade school art projects -- are the inspirations for a printing technique that could rapidly and cheaply produce integrated circuits at least as small as those in today's computer chips. Researchers at Lucent Technologies' Bell Laboratories have developed a way of stamping microscopic circuits onto surfaces such as plastic and silicon. The method calls for etching circuit patterns into a stamp and using glue to transfer gold from the stamp to a surface. The circuit patterns can contain features 10 times smaller than a bacterium. The nanotransfer printing process could eventually be used to make circuits and connectors for plastic electronics, an emerging technology used to make electronic paper and flexible displays.

Splitting Up Cooper Pairs Carbon nanotubes might be used to separate
the entangled electron pairs in superconductors. The usual way of separating
a pair from the pack is to force it to tunnel across an insulating barrier,
