From: Glucose-oxidase like catalytic mechanism of noble metal nanozymes
a Catalytic oxidation of hydroxyl with O2 or ABTS+• as the oxidant. b Colorimetric detection of H2O2 produced by noble metal NPs catalyzing the aerobic oxidation of glucose. c Absorbance of ABTS+• solution in the presence of glucose (50 mM) and different noble metal NPs (PBS, pH = 7.4). d Comparison of the reaction rates for ABTS+• reduction. e pH-dependent reaction rates. f ESR spectra of the DMPO-H adduct from the DMPO and glucose reaction mixture in the presence of different noble metal NPs. g Au NPs-catalyzed ABTS+• reduction in the presence of different substrates. Error bars represent standard deviation from three independent measurements.
