Fluorescence intensity as a function of rhodamine concentration for the peptide and peptide amphiphiles micelles of different compositions. Self-quenching is evident for micelles composed of 100% mol RhoPA (◆), 30% mol RhoPA (■) and 10% mol RhoPA (▲) but not for micelles containing 3% mol RhoPA (●). The solid line represents the calibration curve for unquenched rhodamine-labeled peptide, RhoPep (×). All measurements were performed in PBS, at 25°C (excitation: 560 nm, emission: 580 nm).
