The H2O2 biosensor was prepared by continuous processes: 2,3-dimercaptosuccinic acid (DMSA) self-assembly monolayers gold nanoparticles (AuNPs) film by electrodepositioncovalent immobilization of horseradish peroxidase (HRP). In pH 7.2 phosphoric buffer solution (PBS), the HRP-AuNPs-DMSA-Au electrode exhibited a pair of well-defined cyclic voltammetric peaks in H2O2 solution, and the oxidation peak is about +0.4V versus saturated calomel electrode (SCE). The resulting substrates were characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The biosensor exhibited remarkable sensitivity towards H2O2 and a wide dynamic range of 2-800 μM. The electrode retained 90% of its initial activity after 30 days of storage at 4°C.
