Plasmon resonance energy transfer (PRET) from a single metallic nanoparticle to the molecules adsorbed on its surface has attracted more and more attentions in recent years. Here, a molecular beacon (MB)‐regulated PRET coupling system composed of gold nanoparticles (GNPs) and chromophore molecules has been designed to study the influence of PRET effect on the scattering spectra of GNPs. 2015-08-10 · 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 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. On another front, Fano resonance induced by strong plasmon–exciton coupling provides an efficient channel of coherent energy transfer from metallic plasmons to molecular excitons, and organic dye molecules have a much better injection efficiency in exciton-SSCs than “hot electrons”. 2017-11-09 · Watch an overview of resonance energy transfer between molecules in the presence of plasmonic structures and derive an explicit Förster-type expression for the rate of plasmon-coupled resonance energy transfer (PC-RET). Plasmon-induced resonance energy transfer for solar energy conversion.

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.

The transfer of this energy paired with the natural frequencies of the biomolecules causes an overlap of resonant energy peak positions. Plasmon resonance energy transfer (PRET) from a single metallic nanoparticle to the molecules adsorbed on its surface has attracted more and more attentions in recent years. In these composites, the plasmonic nanoparticles (PNPs) efficiently absorb solar light through localized surface plasmon resonance and convert it into energetic electrons and holes in the nearby semiconductor. This energy transfer from PNPs to semiconductors plays a decisive role in the overall photocatalytic performance.
