Electrical properties of glass at the nanoscale lead to a pump the size of a red blood cell

Abstract:
Researchers have devised a way to fabricate tiny electrodes from glass, harnessing a phenomenon by which nanoscale glass walls can be transformed from insulators to conductors and back again. At larger scales, that phenomenon, known as "dielectric breakdown," leads to excess heating and structural damage, but at the nanoscale the process appears to be harmless and reversible.

Sanghyun Lee of the Pohang University of Science and Technology in South Korea and Ran An and Alan Hunt of the University of Michigan at Ann Arbor announce their finding in a paper published online May 16 in Nature Nanotechnology, along with a prototype application in what may be the smallest man-made pump in existence.
