“…In a number of theoretical and experimental works, FRET has been studied at the level of individual molecules and particles, or for certain (so-called " model") compounds [21,22]. However, for a wide class of compounds, this process is still poorly understood, and the number of articles devoted to the creation of model representations of plasmon-activated energy transfer between organic molecules is relatively small [23][24][25][26].…”

“…In this article, we use the theoretical model previously proposed in [23], which describes the effect of localized plasmon resonance of spherical metal NPs on the development of FRET, and test its modified version using a regularized molecular nanostructure as an example. For this, we used the experimental data published in the article [27], where the plasmon-enhanced Förster resonant energy transfer in donor-acceptor pairs with different energy transfer efficiencies was experimentally studied.…”

To explain the experimentally observed effect of silver nanoparticles on the fluorescence of organic dyes and the nonradiative intermolecular transfer of electronic excitation energy in multilayer nanostructures, the previously proposed theoretical model of plasmon resonance in spherical nanoparticles of metals was used. The rates of radiative and nonradiative (FRET) processes in film structures with Ag nanoparticles were calculated for fluorescein and rhodamine B molecules, as well as for two-component systems fluorescein-nile red (NR) and rhodamine B-NR. A version of the model was used that takes into account the effect of NPs on FRET between molecules, the radiative decay of donor and acceptor molecules, and the energy transfer from the dye to plasmonic nanoparticles. The calculation of the UDA rate for pairs with different energy transfer efficiency showed a greater increase in the UDA parameter for the fluorescein-nile red pair than for the rhodamine B-nile red pair. Estimation of the fluorescence enhancement factor of donor and energy acceptor molecules and the rate of energy transfer from the dye to silver NPs showed their insignificant contribution to the formation of the resulting energy transfer efficiency enhancement in the presence of plasmonic NPs. Keywords: energy transfer, silver nanoparticles, plasmon, model

“…Plasmonic enhancement which resulting from longer range non-radiative energy transfer via nanometal surface energy transfer or localized surface plasmon-coupled FRET effect is a promised method to further improve the fluorescence intensity of the acceptor, extending the application of FRET [10][11][12][13][14][15][16][17]. The FRET between different fluorophores can be modulated by adjacent plasmonic nanocrystals [18][19][20][21][22][23], and the efficiency of FRET and acceptor fluorescence intensity from FRET varies with the size, shape, and location of the metal nanostructure [24][25][26][27]. A two-fold improvement of energy transfer between donor and acceptor has been realized with silver film due to the strong confinement and large propagation length of surface plasmon polaritons [20].…”

“…A two-fold improvement of energy transfer between donor and acceptor has been realized with silver film due to the strong confinement and large propagation length of surface plasmon polaritons [20]. The FRET efficiencies are significantly increased by more than 50% for Cy3-Cy5, and can be increased by up to 61% in G protein-coupled receptor probes in the gold nanoaperture [21,28]. A FRET signal was enhanced to be two times stronger for cell surface imaging and the acceptor QDs' photoluminescence lifetime, increased from 3.38 to 7.52 ns with gold nanoparticles [25].…”

Distance-Dependent Fluorescence Resonance Energy Transfer Enhancement on Nanoporous Gold

Fluorescence resonance energy transfers (FRET) between cyan fluorescent protein (CFP) and yellow fluorescent protein (YFP) on nanoporous gold (NPG) are systematically investigated by controlling the distance between NPG and fluorescent proteins with polyelectrolyte multilayers. The FRET between CFP and YFP is significantly enhanced by NPG, and the maximum enhancement is related to both ligament size of NPG and the distance between NPG and proteins. With the optimized distance, 18-fold FRET enhancement was obtained on NPG compared to that on glass, and the conversion efficiency is about 90%. The potential to tune the characteristic energy transfer distance has implications for applications in nanophotonic devices and provides a possible way to design sensors and light energy converters.

При определенных концентрациях компонентов смеси было обнаружено это влияние, выражающееся в увеличении интенсивности сенсибилизированной флуоресценции акцептора при одновременном тушении флуоресценции донора.…”

Spectral-luminescent properties of benzene and toluene solutions of poly[2-methoxy, 5-(2’- ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV) with additives of single - and double-walled carbon nanotubes (CNTS) were studied in order to detect manifestations of plasmon properties of CNTS in the luminescence of MEH-PPV solutions. It was found that the dependence of the luminescence intensity of the polymer solution on the CNT concentration is non-monotonic: with an increase in the number of dissolved nanotubes, this intensity initially increases, and then decreases. At the same time, the deformation of the light spectrum itself practically does not take place. The effect was observed as when using a single-walled CNT (swcnt) and double wall (DWNT). The depth of modulation of the glow intensity in the case of DPT was higher than in the case of ount. To explain the observed dependencies, various variants of the electro-dynamic model of activation-quenching of MEH-PPV luminescence by carbon nanotubes are proposed. Direct modeling of near and far field characteristics is performed based on Maxwell's equations, for numerical solution of which the finite difference method in the time domain (FDTD) is used. Computational experiments have shown that CNTS with a MEH-PPV layer have directional antenna properties, acting as a kind of waveguides. Thus, the energy of radiation that reached the far zone in the direction of the nanotube axis was an order of magnitude higher than in the case of a solution without CNT. Fan-type electromagnetic waves emanating from both ends of the nanotube were detected, as well as the stage of plasmon waves beating, which characterizes the nanotube as a waveguide. Molecular dynamic modeling of the configurations of the adsorbed MEH-PPV chain in various solvents, both on a single CNT and on two parallel CNTS with a variation in the distance between them, was performed. It was found that as the distance between CNTS increases, the conformational structure of MEH-PPV becomes more loose: there is an increase in the number of large loops of the macrocycle in the bulk phase of the solution
