Fig. 8. Chemodynamic effects of Cu-CS/SA hydrogels
(a) UV-Vis absorption spectra of TMB solutions with pH 6.0 and H2O2 (100 mmmol/L) after adding Cu-CS/SA hydrogel (0.1 g/mL) with different contents of Cu-CS nanorods for 60 min; (b) UV-Vis absorption spectra changes of TMB solutions with time after adding 20%-Cu-CS/SA hydrogel (0.1 g/mL) under a condition of pH 6.0 and H2O2 (100 mmmol/L); (c) UV-Vis absorption spectra changes of TMB solutions with time after adding 20%-Cu-CS/SA hydrogel (0.1 g/mL) under a condition of pH 6.0; (d) UV-Vis absorption spectra changes of TMB solutions with time under a condition of pH 6.0 and H2O2 (100 mmmol/L); (e) Absorbance changes at 652 nm versus time for TMB solutions with 20%-Cu-CS/SA hydrogel under pH 6.0 or pH 7.4 conditions and with or without H2O2; (f) Absorbance changes at 652 nm versus time for TMB solutions with different concentrations of H2O2 at pH 6.0 after adding 20%-Cu-CS/SA hydrogel (0.1 g/mL).
