Inspired by a cotton candy machine, engineers put a new spin on creating tiny nanofibers

Hailed as a "cross between a high-speed centrifuge and a cotton candy machine," a new, practical technology for fabricating tiny nanofibers has been developed by bioengineers. The reference to the fairground treat of spun sugar is deliberate, as the device literally -- and just as easily -- spins, stretches and pushes out 100 nanometer-diameter polymer-based threads using a rotating drum and nozzle.
