Molecular Nanophotonics

Molecular Nanophotonics

We're an experimental research effort in UC Berkeley's College of Chemistry and at Lawrence Berkeley National Lab. We use concepts from quantum optics and nanophotonics in the chemical sciences with two objectives: advancing methods in single-molecule spectroscopy, microscopy, and sensing; and designing material systems with coherent modes of action useful in quantum information science and energy transduction.
