英文摘要 | A third-generation hydrogen peroxide biosensor was prepared by immobilizing horseradish peroxidase (hrp) on a gold electrode modified with silver nanoparticles. a freshly-cleaned gold electrode was first immersed in a cysteamine-ethanol solution, and then silver nanoparticles were immobilized on the cysteamine monolayer, and finally hrp was adsorbed onto the surfaces of the silver nanoparticles. this self-assemble process was examined via atomic force microscopy (afm). the immobilized horseradish peroxidase exhibited an excellent electrocatalytic response toward the reduction of hydrogen peroxide. the linear range of the biosensor was 3.3 mu m to 9.4 mm, and the detection limit was estimated to be 0.78 mu m. moreover, the biosensor exhibited a fast response, high sensitivity, good reproducibility, and long-term stability. |
