• surface-enhanced fluorescence (SEF). This method is based on designing nanosurfaces and then using them near the emitter in order to control its local electromagnetic environment [106]. The molecules that are in the vicinity of nanosubstrates or adsorbed to their surface suffer a modification of their

Both methods rely on the high electromagnetic fields created at locations on the surface of plasmonic metal nanoparticles, depending on the geometry of the nanoparticles, their

These enhanced local electromagnetic fields of the different plasmonic structures have been applied to enhance optical transitions such as in Raman spectroscopy [12] (as surface enhanced Raman scattering – SERS) and fluorescence [13] (as surface enhanced fluorescence – SEF) where the

Due to its extreme sensitivity, fluorescence allows

• evanescent decay on the metal surface. This strong field enhancement by the evanescent field can be employed for an effective enhancement of the weak Raman cross section (surface-enhanced Raman spectroscopy – SERS) [25] and also of the fluorescence signal (surface-enhanced fluorescence – SEF) [26].
