Abstract: Abstract: It was found that Fe3O4 nanoparticles (Fe3O4 NPs) possess intrinsic enzyme mimetic activity similar to that found in natural peroxidase. Here, we applied Fe3O4 NPs to the construction of efficient electrochemical sensor to detect the concentration of hydrogen peroxide. The sensor was fabricated with layer-by-layer assembly of Fe3O4 NPs and poly(diallyldimethylammonium chloride) (PDDA) through the electrostatic interaction, and the multilayer film was characterized with UV–vis absorption spectra, atomic force microscopy, and cyclic voltammetry. Moreover, the sensor showed prominent electrocatalytic activity toward the reduction of H2O2, and the interferences of ascorbic acid (AA) and uric acid (UA) were completely avoided. Unlike the inherent instability of enzyme, Fe3O4 NPs-based sensor demonstrated outstanding stability. [Copyright &y& Elsevier]
