Light-sensitive Photoswitches Could Restore Sight to Those with Macular Degeneration

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.


One major goal of the UC Berkeley-LBNL Nanomedicine Development Center is to equip cells of the retina with photoswitches, essentially making blind nerve cells see, restoring light sensitivity in people with degenerative blindness such as macular degeneration.
