Nanophotonic control of the Förster resonance energy transfer efficiency.
We have studied the influence of the local density of optical states (LDOS) on the rate and efficiency of Förster resonance energy transfer (FRET) from a donor to an acceptor. The donors and acceptors are dye molecules that are separated by a short strand of double-stranded DNA. The LDOS is controlled by carefully positioning the FRET pairs near a mirror. We find that the energy transfer effici...
متن کاملModification of Förster Resonance Energy Transfer Efficiency at Interfaces
We present a theoretical study on the impact of an interface on the FRET efficiency of a surface-bound acceptor-donor system. The FRET efficiency can be modified by two effects. Firstly, the donor's electromagnetic field at the acceptor's position is changed due to the partial reflection of the donor's field. Secondly, both the donor's and the acceptor's quantum yield of fluorescence can be cha...
متن کاملNanophotonic enhancement of the Förster resonance energy-transfer rate with single nanoapertures.
Tailoring the light-matter interaction and the local density of optical states (LDOS) with nanophotonics provides accurate control over the luminescence properties of a single quantum emitter. This paradigm is also highly attractive to enhance the near-field Förster resonance energy transfer (FRET) between two fluorescent emitters. Despite the wide applications of FRET in nanosciences, using na...

متن کاملFörster resonance energy transfer photoacoustic microscopy.
Förster, or fluorescence, resonance energy transfer (FRET) provides fluorescence signals sensitive to intra- and inter-molecular distances in the 1 to 10 nm range. Widely applied in the fluorescence imaging environment, FRET enables visualization of physicochemical processes in molecular interactions and conformations. In this paper, we report photoacoustic imaging of FRET, based on nonradiativ...
