Fluorescence spectra of BSA solution (1 × 10−6 M) in the absence and presence of different concentrations of SB (T = 298 K, pH = 7.40, λ ex = 285 nm). a From a to i, the SB concentration increased from 0 to 8.0 × 10−6 M, with a step size of 1.0 × 10−6 M. b Quenching effect of Stern–Volmer on BSA induced by SB
