Lasers used to spatially and temporally control the release of a tagged protein inside a cell

Optogenetics, which uses light to control , is poised to become an important technology in and beyond. The in UC Santa Barbara’s Department of Chemistry and Biochemistry has made a major contribution to this emergent field by developing a light-activated nanocarrier that transports proteins into cells and releases them on command. The findings appear in the journal Molecular Pharmaceutics.
