Researchers Rev Up Electric Nano-Motors

[TechNews]

 Researchers at Tufts University announced Sunday they've created an electrical motor many thousands of times smaller than the width of a single human hair, a breakthrough they claim could eventually lead to innovations in healthcare and technology. The microscopic motor is the size of a single molecule and is electrically charged, an innovative feat since previous single-molecule-sized motors were powered by chemicals or light. With a light or chemically charged motor, scientists struggle with precision in adding chemicals to a clump of trillions of molecules.
