High-spatial resolution fluorescence imaging on a high-density gold nanoelectrode array was achieved by anchoring fluorescent molecules to limit diffusion. The sensitivity of fluorescence imaging was effectively improved by using an ionic liquid with a refractive index matching the optical system. Spatially resolved imaging of electrochemical reactions on a single nanoelectrode modified with a single Pt nanoparticle was also demonstrated.
