Magnetic Nanovoyages in Human Blood

April 21, 2014

(Nanowerk) – While nanotechnology researchers have made great progress over the past few years in developing self-propelled nano objects, these tiny devices still fall far short of what their natural counterparts’ performance. Today, artificial nanomotors lack the sophisticated functionality of biomotors and are limited to a very narrow range of environments and fuels.  In another step towards realizing Richard Feynman’s vision of tiny vessels roaming around in human blood vessels working as surgical nanorobots, researchers at the Indian Institute of Science (IISc) in Bangalore have now demonstrated, for the first time, externally driven nanomotors that move in undiluted human blood.
