“Background One of the most commonly used approaches to tune the fluorescence properties of fluorophores is to couple them to plasmonic excitations in metallic nanoparticles [1]. Large variations of shapes and sizes of metallic nanostructures provide almost infinite space for spectral engineering of optical properties of emitters, ranging from control of the fluorescence intensity, fluorescence decay dynamics, as well as the emission spectrum itself. Remarkable effects of plasmon coupling have been demonstrated on a single-molecule level, where a fluorophore was approached in a controllable way by a spherical metallic nanoparticle [2]. For large distances, the emission remained unaffected;

however, Thymidylate synthase as the separation decreased, a strong enhancement of the fluorescence emission has been measured. Upon further reduction of the separation between the fluorophore and metallic nanoparticle, the intensity of the fluorescence emission decreased rapidly. This result demonstrates allimportant effects of plasmon coupling in such experimental configuration, and they are associated with modifications of fluorescence quantum yield of the fluorophore, enhancement of its excitation rate, and quenching due to nonradiative energy transfer to the metallic nanoparticle. As these processes compete against each other, in order to achieve strong enhancement of the fluorescence intensity, it is crucial to put attention to the geometry of the hybrid plasmonic nanostructure, in particular to the control of the separation between fluorophores and metallic nanoparticles.
