Exploring Photoswitchable Plasmon-Molecule Interactions at the Single-Molecule and Single-Nanoparticle Levels

ORAL

Abstract

Through synergizing the responsiveness of functional molecules and the plasmon-assisted nanoscale localization of light, hybrid nanosystems consisting of molecules and metal nanoparticle have important applications in biochemical detection, drug delivery, and energy conversion. Single-molecule and single-nanoparticle studies of the hybrid nanosystems help eliminate the inevitable heterogeneity from ensemble measurements and provide new insights into the structure-property relations. Along this line, herein, we report our recent advances in designing, measuring and controlling two types of photoswitchable metal-nanoparticle-molecule nanosystems at the single-molecule and single-nanoparticle levels: (1) azobenzene molecules on single metal nanoparticles; and (2) spiropyran molecules on single metal nanoparticles.
