Fluorescence Resonance Energy Transfer (FRET)

Fluorescence Resonance Energy Transfer (FRET). FRET. Resonance energy transfer can occur when the donor and acceptor molecules are less than 100 A of one another Energy transfer is non-radiative which means the donor is not emitting a photon which is absorbed by the acceptor
