Förster resonance energy transfer (FRET) is a physical phenomenon that describes the transfer of energy from an excited donor molecule to an acceptor molecule through non-radiative dipole-dipole interactions. This process occurs when the two molecules are in close proximity, typically within 1 to 10 nanometers.
