Enzymatic activity characterization of Pt/SAE. A Schematic illustration of multiple enzyme-mimetic activities of Pt/SAE. B Quantitative assessment of SOD-like activity. C Spectrophotometric comparison of SOD-mimetic activity of different concentrations of Pt/SAE at 450 nm. D Quantitative evaluation of CAT-mimetic activity. E Comparative analysis of CAT-mimetic activity among different concentrations of Pt/SAE. F Quantitative assessment of HORAC. G Comparative analysis of HORAC among different concentrations of Pt/SAE. H Quantitative assessment of radical-scavenging activity. I Spectrophotometric comparison of ABTS radical-scavenging activity of different concentrations of Pt/SAE at 750 nm. n = 3. p-values are calculated using the Student’s two-tailed t-test, ns: no significance, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
