In Nano Letters, researchers at the University of Fribourg and IFIMAC report on the modification of the emission of individual dyes placed at the vicinity of gold nanorod antennas. The work make use of DNA origami to precisely place single dyes at different positions, probing the plasmonic-enhanced density of photonic strates around the nanostructure. In some configurations, the drastic alteration of the fluorescence spectrum suggests the violation of Kasha’s rule. [Full article]
