Dose dependent quenching of pyrene fluorescence in OS liposomes. Addition of pyrene to aqueous solution containing OS liposomes caused substantial quenching of pyrene’s fluorescence in a dose dependent manner (A); increasing liposomes concentration caused a redshift in emission intensity and increased the I384/I375 intensity ratio (B). The critical micellar concentration (CMC) is estimated from graph B and was found to be 9.2 ± 2.9 μg/ml.
