Förster resonance energy transfer (FRET) between tryptophan (W23) of the peptide/peptide amphiphile and dansyl fluorophores immobilized on the surface of liposomes. (A) Fluorescence spectra showing both tryptophan and dansyl emission upon excitation at 280nm for suspensions of liposomes containing 5% dansyl PS in the presence of PA (○), Pep (□) or in their absence (+) (B) Graph showing efficient FRET from tryptophan to dansyl in the presence of the peptide amphiphile but not of the peptide.
