“…On the contrary, large nanoparticles, in which scattering processes are predominant over absorptive ones, tend to increase the fluorescence of interacting emitters, behaving such as small antennas. Such a phenomenon is sometimes called "Surface Plasmon Coupled Emission" and is extremely useful for high-resolution sensing applications based on fluorescence [31][32][33][34][35][36][37].…”

Dipole–Dipole interactions (DDI) constitute an effective mechanism by which two physical entities can interact with each other. DDI processes can occur in a resonance framework if the energies of the two dipoles are very close. In this case, an energy transfer can occur without the need to emit a photon, taking the name of Förster Resonance Energy Transfer (FRET). Given their large dependence on the distance and orientation between the two dipoles, as well as on the electromagnetic properties of the surrounding environment, DDIs are exceptional for sensing applications. There are two main ways to carry out FRET-based sensing: (i) enhancing or (ii) inhibiting it. Interaction with resonant environments such as plasmonic, optical cavities, and/or metamaterials promotes the former while acting on the distance between the FRET molecules favors the latter. In this review, we browse both the two ways, pointing the spotlight to the intrinsic interdisciplinarity these two sensing routes imply. We showcase FRET-based sensing mechanisms in a variety of contexts, from pH sensors to molecular structure measurements on a nano-metrical scale, with a particular accent on the central and still mostly overlooked role played between a nano-photonically structured environment and photoluminescent molecules.

“…The SPCE in the respect of a geometric light path can be understood as a reverse process of SPFS. ,, There is a reverse pathway to proceed as shown in Figure A in comparison with the SPFS (Figure E). The p-polarized incoming light is heading in the opposite direction (arrow) to intentionally excite the local fluorophore, irrespective through a direct excitation or an excitation via the resonant surface plasmon at a metal–medium interface. , The fluorescence emission arising from these excited-state fluorophores here tends to couple the surface plasmons, but it is not to be measured as signaling out. − The coupling phenomenon nearby the interface induces the fluorescence radiation into the prism substrate with a very narrow angular distribution.…”

The integration of surface plasmon resonance and fluorescence yields a multiaspect improvement in surface fluorescence sensing and imaging, leading to a paradigm shift of surface plasmonassisted fluorescence techniques, for example, surface plasmon enhanced field fluorescence spectroscopy, surface plasmon coupled emission (SPCE), and SPCE imaging. This Review aims to characterize the unique optical property with a common physical interpretation and diverse surface architecture-based measurements. The fundamental electromagnetic theory is employed to comprehensively unveil the fluorophore−surface plasmon interaction, and the associated surfacemodification design is liberally highlighted to balance the surface plasmon-induced fluorescence-enhancement efforts and the surface plasmon-caused fluorescence-quenching effects. In particular, all types of surface structures, for example, silicon, carbon, protein, DNA, polymer, and multilayer, are systematically interrogated in terms of component, thickness, stiffness, and functionality. As a highly interdisciplinary and expanding field in physics, optics, chemistry, and surface chemistry, this Review could be of great interest to a broad readership, in particular, among physical chemists, analytical chemists, and in surface-based sensing and imaging studies.
