Description
Summary:The reductive detection method of hydrogen peroxide(H<sub>2</sub>O<sub>2</sub>) was developed by using a composite of molybdenum disulfide(MoS<sub>2</sub>), gold(Au) nanoparticles, and platinum(Pt) nanoparticles as the substrate and indium tin oxide <b>(</b>ITO<b>)</b> as the electrode. The constructed biosensor based on Pt-Au-MoS<sub>2</sub>-ITO laid a foundation for the portable operation of reduction detection of H<sub>2</sub>O<sub>2</sub>.The electrochemical deposition method was adopted to prepare the electrode material. Traditional electrochemical methods such as cyclic voltammetry(CV) and chronoamperometry(CA) were used to characterize the electrochemical properties of the biosensors and field emission scanning electron microscope(FE-SEM) diagrams were used to characterize the surface appearance of the biosensors. In this work, a biosensor for reduction detection of H<sub>2</sub>O<sub>2</sub> with high detection limit, high sensitivity and wide detection range was constructed.
