What is fluorescence resonance energy transfer?

Förster resonance energy transfer, resonance energy transfer or electronic energy transfer is a mechanism describing energy transfer between two light-sensitive molecules.

Fluorescence Resonance Energy Transfer (FRET) is a physical phenomenon first described over 50 years ago, that is being used more and more in biomedical research and drug discovery today. FRET is the radiationless transmission of energy from a donor molecule to an acceptor molecule.

The technique of fluorescence resonance energy transfer (more commonly referred to by the acronym FRET), when applied to optical microscopy, permits

By RB Sekar · 2003 · Cited by 931 — Fluorescence resonance energy transfer (FRET)* is a distance-dependent physical process by which energy is transferred nonradiatively from an excited molecular fluorophore (the donor) to another fluorophore (the acceptor) by means of intermolecular long-range dipole–dipole coupling."FRET imaging microscopy · FRET data analysis · FRET applications in cell...

Fluorescence resonance energy transfer (FRET) is a tool used for determining the distance between two fluorophores. FRET is the nonradiative transfer of energy from donor to acceptor molecules and is inversely proportional to the sixth power of the distance, as shown on the plot in the middle panel.
