5110	200	GeO2	Colorimetric Assay of OPs	paraoxon	Color	0.1-50	pM	14	fM		Typically, 100 µL of different concentrations of paraoxon (0, 0.1, 2, 5, 10, 15, 30, 50, 70, 100 pm) were mixed with 20 µL of PB solutions (0.1 m, pH 8.0) containing AChE (10 µg mL−1). After the incubation for 20 min at 37 °C, 20 µL of ATCh solution (10 mm) and 20 µL of GeO2 nanozymes solution (1 mg mL−1) were added into the above mixture respectively for another 20 min incubation. The residual GeO2 nanozymes was collected by centrifugation, and added into 200 µL of acetate buffer (pH 4.0, 0.1 m) containing TMB (0.6 mm) and H2O2 (1.2 mm). Finally, the absorbance of the above reaction was measured after 30 min. Each experiment was repeated three times. The LOD was calculated by the equation LOD = (3σ/s), where σ is the standard deviation of blank signals and s is the slope of the calibration curve.
