^aIntegrated intensity (peak intensity) relative to that of the phenylalanine band at 1002 cm^-1. N. D. = not detected. The concentration of BSA was 1.5 × 10^-5 mol/L, and DMSO was kept at 10%. Q2, Q6, and Q10 indicate concentrations of Q at 3.0 × 10^-5, 9.0 × 10^-5, and 15.0 × 10^-5 mol/L, respectively.
