Fig. 2From: Hot-Electron-Activated Peroxidase-Mimicking Activity of Ultrathin Pd NanozymesThe peroxidase-mimicking activity of Pd NSs. a-b Typical UV-visible absorption spectra of different samples under visible light and dark conditions. c Temperature and pH effect on peroxidase-mimicking activity. d Time courses for peroxidase-mimicking activity. e The peroxidase-like mechanism of Pd NSs under dark and visible light. Experimental conditions: visible light = λ ≥ 400 nm, TMB = 0.7 mM, H2O2 = 50 mM, temperature =25 °C, Pd NSs = 12.6 μg/mL, and phosphate buffer solution (0.1 M, pH 4)Back to article page
