Abstract

Single-molecule fluorescence is a powerful tool for imaging structures below the standard diffraction limit of light. The resolution gain comes from fitting the emission of isolated fluorophores, and localization accuracy improves with number of photons detected. Here, we control single-molecule emission by coupling fluorescence to gold nanoparticle local plasmon resonances. These strongly localized electromagnetic modes are generated by the interaction of light with particles smaller than the incident wavelength. We discuss the effects of this plasmonic mode coupling on the fluorescence intensity and lifetime of dye molecules and quantum dots.
