Controlling Plasmon-Fluorophore Coupling Using DNA-Nanoparticle Hybrids
October 16th, 2019 PETER ZIJLSTRA Eindhoven University of Technology

Plasmon resonances dramatically modify the photophysics of nearby fluorophores. Exploiting this process requires accurate control over the position and residence time of the fluorophore with respect to the particle. I will outline the use of DNA-nanoparticle hybrids to study plasmon-fluorophore coupling at the single-particle and single-molecule level. I will first describe how to control and quantify the DNA-nanoparticle stoichiometry at the single-molecule level. I will then discuss two applications of such nanoparticle-hybrids: for optical imaging of particle geometry using super-resolution microscopy, and for ultrabright single-molecule emission with enhanced saturation intensities.
