Fluorescence intensity ratios of first and third emission peaks of pyrene versus SAP conjugate concentration. The concentration of pyrene was kept constant at 2 µM, while that of the SAP conjugate was ranging between 0.0 and 1.2 mM. After an excitation at 330 nm, change in the ratios of fluorescence emission intensity at 370 nm (I1) and 380 nm (I3), started to occur at 0.13 mM, indicating the critical micelle concentration (CMC) of SAP conjugate
