Angular modulation of single-molecule fluorescence by gold nanoparticles on DNA origami templates

Angular modulation of single-molecule fluorescence by gold nanoparticles on DNA origami templates

We study the angular fluorescence intensity modulation of a single dye positioned near a spherical gold nanoparticle, induced by rotation of linearly polarized excitation light. Accurate positioning and alignment of nanoparticle and fluorophore with respect to each other and the incoming electric fi...
