With the capability of surface plasmons in manipulating light at the nanoscale, molecular plasmonics bridges size mismatch between light and molecules for new physics and functions. We aim to advance fundamental understanding of the molecule-plasmon coupling with single-nanoparticle and single-molecule measurements and to develop novel optical materials and devices. We have recently developed rewritable nanophotonics, moire chiral metamaterials, and chiral sensors.
