New process makes nanofibers in complex shapes and unlimited lengths

CHAMPAIGN, Ill. The continuous fabrication of complex, three-dimensional nanoscale structures and the ability to grow individual nanowires of unlimited length are now possible with a process developed by researchers at the University of Illinois. Based on the rapid evaporation of solvent from s...

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

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 b...
