Mapping the fluorescence performance of a photochromic-fluorescent system coupled with gold nanoparticles at the single-molecule-single-particle level
Single-molecule (SM) fluorescence microscopy was used to investigate the photochromic fluorescent system spiropyran-merocyanine (SP ↔ MC) interacting with gold nanoparticles (AuNPs). We observe a significant increase in the brightness of the emissive MC form, in the duration of its ON time, and in t...
