FRET Peptides

FRET (Fluorescence Resonance Energy Transfer) is a distance-dependent dipole-dipole interaction, this interaction results in energy transfer from initial excited donor molecules to acceptor molecules without photon emission. This method can detect the molecular interactions in the nano-meter range.

Fluorescence Resonance Energy Transfer is a detection method of the ‘distance-dependent’ interaction between the two distinct dye molecules in excited states: the fluorophore and the quencher.
