Detecting bacteria, viruses and other dangerous substances in 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," says 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."
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.
