The amperometric current is linearly related to the concentration of H2O2 in the range from 0.2mM to 2mM, the regression equation is y = -0.5-1.82x, the correlation coefficient is 0.998 (n = 3), and the detection limit is 0.01mM (S/N = 3). The sensor exhibits favorable selectivity and excellent stability. Figure Using the peroxidase mimic property of Fe3O4 magnetic nanoparticles (MNPs), a sensitive electrochemical method with favorable analytical performance for the determination of hydrogen peroxide (H2O2) was developed.
