Herein, the polypyrrole decorated with gold–silver nanoparticle (Ag–Pd NPs) nanocomposite modified glassy carbon was used for the determination of hydrogen peroxide. Electrochemical experiments indicated that the proposed sensor possesses an excellent sensitivity toward the reduction of hydrogen peroxide. The resulting sensor exhibited a good response to hydrogen peroxide over linear range from 0.05 to 90.0 μM with a limit of detection of 0.02 μM, good reproducibility, long-term stability and negligible interference from ascorbic acid, uric acid and dopamine. The proposed sensor was successfully applied to the determination of hydrogen peroxide in human serum sample. Pd-Ag nanoparticles; Polypyrrole; Hydrogen peroxide; Electrochemical sensor
