Biodegradable napkin -- featuring sensitive nanofibers -- may quickly detect biohazards

ITHACA, N.Y. -- 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, says a researcher from Cornell University.

"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. "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 at the American Chemical Society's national meeting today (Sept. 11) in San Francisco.

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.

In work conducted with Yong Joo, assistant professor of chemical and biomolecular engineering, and Antje Baeumner, associate professor of biological and environmental engineering, both at Cornell, Frey developed nanofibers with platforms made of biotin, a part of the B vitamin complex, and the protein streptavidin, which can hold the antibodies. Composed of a polymer compound made from corn, the nanofibers could be incorporated into conventional paper products to keep costs low. Nanofibers, with diameters near 100 nanometers (a nanometer is one-billionth of a meter, or about three times the diameter of an atom), provide extremely large surface areas for sensing and increased absorbency compared with conventional fibers.
