Fig. 8. The UV-vis absorption spectra of BSA in the absence and presence of different concentrations of ASN. From (a–f), the concentrations of ASN were varied from 0 to 3.0 × 10−5 mol L−1 at 0.6 × 10−5 mol L−1 intervals. Curve g showed the UV-vis absorption spectra of ASN only at the concentration of 0.6 × 10−5 mol L−1, CBSA = 0.6 × 10−5 mol L−1, T = 298 K.
