Super-resolution fluorescence imaging is used as an optical readout to investigate single molecule electrochemical events on the surface of plasmonic nanoparticle electrodes. The fluorescence of single Cresyl Violet molecules is monitored as the molecule changes between an emissive and non-emissive form based on its redox state. This provides the ability to monitor site-specific single molecule oxidation events on the surface of nanoparticle electrodes, providing powerful information about intra-particle heterogeneity and its impact on electrochemical reactions.
