Macular Degeneration :: Photoswitches could restore sight to blind retinas
A research center newly created by the University of California, Berkeley, and Lawrence Berkeley National Laboratory (LBNL) aims to put light-sensitive switches in the body’s cells that can be flipped on and off as easily as a remote control operates a TV. Optical switches like these could trigger a chemical reaction, initiate a muscle contraction, activate a drug or stimulate a nerve cell – all at the flash of a light.
