Fluorescence resonance energy transfer luminescence

Fluorescence resonance energy transfer (FRET) luminescence occurs when donor phosphor decreases its emission intensity and luminescent lifetime, while acceptor phosphor lights up. As the precondition of FRET, the donor emission and the acceptor absorption require adequate spectra overlaps. The spatial distance of donor-acceptor pair is the second factor. Only within a small range, the energy could be transferred from donors to...

There are two main types of RET, bioluminescence resonance energy transfer (BRET) and fluorescence resonance energy transfer (FRET). In the former, the donor molecule is luminescent (27,28)... 

Quenching of the luminescence of the QDs by an electron transfer (ET) mechanism, or by a fluorescence resonance energy transfer (FRET) route, could reflect the formation of a recognition pair, or may be used to follow the dynamics of chemical processes that occur on the modified QDs. In these systems, the sensing events or the respective biocatalytic transformations involve the association/ dissociation of quencher/FRETacceptor units that electronically couple with the QDs. 

Time- and frequency-domain fluorescence methods have been used in different fields for several purposes, such as distinguishing sample constituents whose fluorescence spectra overlap one another, to distinguish the fluorescence of an analyte from background scattering or luminescence of other sample constituents, in combination with fluorescence resonance energy transfer (FRET) assays to combine the benefits of FRET and time-resolved fluorescence. A listing of some selected applications is given in Table 3.

FRET (fluorescence resonance energy transfer) between luminescent semiconductor nanoparticles and other fluorescent molecnles such as amino acid residues in proteins, etc. that are attached to the particles has also been observed. Examples include...
