    • The gradual decrease of the intensity with increasing SCM concentration mostly resulted from the weakening of the emission from the nonpolar excited state of ANS, as revealed from peak fitting. This change was most likely due to a slightly lower binding affinity of the SCM for the nonpolar state than for the polar state. As the concentration of the SCM increases, more binding sites became available. As more of the ANS probes occupied the polar binding sites, the overall emission intensity decreased gradually.
