Photoswitch Biosciences


Photoswitch Biosciences was formed to develop and commercialize applications of photoswitch molecules. We are located in Menlo Park and are part of the QB3 Mission Bay Network.


Photoswitches are a family of small-molecules designed to photo-modulate the activity of specific signaling proteins: One color turns the protein ‘on’; a different color turns it ‘off’. Photoswitches were conceived at the Nanomedicine Development Center for the Optical Control of Biological Function at UC Berkeley.
