a Schematic illustration of glucose detection by the typical colorimetric assay with Au as a GOD mimic and Prussian blue as an HRP mimic. b ABTS+• as an electron acceptor and colorimetric indicator for glucose detection. c ABTS oxidation catalyzed by Au and PB with O2 and different concentrations of glucose (left). ABTS+• reduction catalyzed by Au NPs with different concentrations of glucose (right). d Linear plot of absorbance intensity versus glucose concentration. All experiments were conducted in PBS (50 mM, pH = 7.4). Error bars represent standard deviation from three independent measurements.
