BEIJING (XFN-ASIA) – China is making rapid advances in the field of nanotechnology and the US should monitor China’s progress in order to maintain a competitive edge in the cutting-edge scientific research sector, the Wall Street Journal reported, citing a visiting US commerce official. China is one of the players that is gaining on us. We are wise to take a look at what they are doing that’s been successful, and see how it might apply to improve our system,’ the newspaper said, citing Robert Cresanti, undersecretary for technology at the US Department of Commerce.

Cresanti, who is in Beijing to meet with Chinese policymakers, said China’s gains were obvious.

‘We saw labs today full to the rafters with scientists and machinery. There has also been a dramatic increase in the quality and quantity of papers on nanotechnology published by Chinese scientists,’ he said.

CU biodegradable wipe would quickly detect biohazards, from avian flu to E. coli
By Susan Lang

Detecting bacteria, viruses and other dangerous substances in hospitals, airplanes and other commonly contaminated places could soon be as easy as wiping a napkin or paper towel across a surface.

“It’s very inexpensive, it wouldn’t require that someone be highly trained to use it, and it could be activated for whatever you want to find,” said Margaret Frey, the Lois and Mel Tukman Assistant Professor of Fiber Science and Apparel Design at Cornell University. “So if you’re working in a meat-packing plant, for instance, you could swipe it across some hamburger and quickly and easily detect E. coli bacteria.” She reported on the research Sept. 11 at the American Chemical Society’s national meeting.

Once fully developed, the biodegradable absorbent wipe would contain nanofibers containing antibodies to numerous biohazards and chemicals and would signal by changing color or through another effect when the antibodies attached to their targets. Users would simply wipe the napkin across a surface; if a biohazard were detected, the surface could be disinfected and retested with another napkin to be sure it was no longer contaminated…..
