Electrochemical Detection of Hydrogen Peroxide

We designed a hydrogen peroxide biosensor. Electrochemical techniques such as differential pulse voltammetry (DPV) and cyclic voltammetry (CV) was used to check the property of biosensor. The hydrogen peroxide-designed biosensor displayed a linear range from ۰.۲ to ۱۴ nM (R۲ = ۰.۹۹), a detection limit of ۱.۲۹ nM (S/N = ۳) and sensitivity of -۰.۱۱۰۵ A/nM. This biosensor can detect hydrogen peroxide with high sensitivity, selectivity, and low detection limit.
