a Schematic representation of colorimetric glucose detection using glucose oxidase (GOx) and hemin-PNTs-catalyzed reactions. The UV‒vis spectrum of hemin-PNTs (3.3 μg/mL) at various concentrations of b H2O2 and d glucose with a constant amount of TMB (3 mM). The linear calibration curve for c H2O2 and e glucose. Data represent means ± SDs. (n = 3)
