One promising direction that we examine in this Perspective is resonance energy transfer between molecules in the presence of plasmonic materials.21−45 Resonance energy transfer (RET), including radiative and radiativeless mechanisms, is a ubiquitous photophysical process. We describe the development of innovative plasmon resonance energy transfer (PRET)-based molecular imaging of biomolecules in living cells. Our strategy of in vivo PRET imaging relies on the resonant plasmonic energy transfer from a gold nanoplasmonic probe to conjugated target molecules, which creates “quantized quenching dips” within the Rayleigh scattering spectrum of the probe. Plasmon-induced resonance energy transfer (PIRET) differs from FRET because of the lack of a Stoke's shift, non-local absorption effects and a strong dependence on the plasmon's dephasing rate and Plasmon Resonance Energy Transfer occurs when nanoparticles are connected to molecular chromophores (an atom or molecule whose presence is responsible for the color of the compound), then the plasmon resonance energy can be transferred to the molcular chromophore.

Surface plasmon energy can be transferred from Au nano-particles (AuNPs) as donors to dye molecules or semi-conductors as acceptors, through so-called plasmon-induced resonance energy transfer (PIRET) or plasmon resonance energy transfer (PRET).1−7 Compared with dye molecule donors in Förster resonance energy transfer (FRET), AuNP By tethering resonant biomolecules to Au nanoprobes, the binding events of Cytochrome c onto 50-nm Au nanoprobes yield characteristic spectral dips in scattering spectra of Au nanoprobes due to plasmon resonance energy transfer (PRET). Enhanced Förster resonance energy transfer was found for donor–acceptor pairs of cationic dyes in the presences of silver nanoparticles (NPs) in solution. This enhancement is attributed both to an increase in the fluorescence intensity of the dyes and the direct effect of local plasmon resonance of the NPs on the energy transfer rate constant.

Plasmon resonance energy transfer is the energy stored in the collective movement of free electrons in metallic nanoparticles being transferred to the adsorbed chemical and biomolecules with match electronic transition energy. As all quantum phenomena, resonance energy transfer is a matter of probability. Having dipole-dipole resonance by ensuring a strong spectral overlap between the emission band and the plasmon band increases the probability of energy transfer and has been demonstrated experimentally [ 36, 37 Plasmonics offer a promising avenue to overcome this problem and achieve high efficiency. By placing the plasmon resonance at the excitation frequency, both the absorption and energy transfer Here the bulk plasmon resonance is induced or suppressed to manipulate the propagation of light.
