Synchronous fluorescence spectra of SOD in the presence of AgNPs (a, d) or Ag+ (b, e) at different concentrations; F/F0 (Synchronous fluorescence spectral peak) of SOD in the presence of AgNPs or Ag+ at different concentrations. Condition: T = 298 K; pH 7.4; C(SOD) = 6×10−6 mol/L. a, b, d C(AgNPs/Ag+, × 10−6 g/mL), a–f: 0, 4, 8, 12, 16, 20; AgNPs/Ag+ only: C(SOD) = 0, C(AgNPs/Ag+)=20 × 10−6 g/mL; e C(AgNPs/Ag+, × 10−6 g/mL), a–b: 0, 4; Ag+ only: C(SOD) = 0, C(Ag+)=4 × 10−6 g/mL
