| Abstract: | The hollow Pd nanoparticles were synthesized and characterized by TEM. A novel biosensor based on hollow palladium and glucose oxidase immobilized on the surface of glassy carbon electrode for glucose detection was developed. The glucose can be determined by detecting H202 generated in enzyme reaction due to the electro- catalytic activity of hollow Pd toward H202. Under the optimal conditions, a linear dependence of the catalytic cur- rent upon glucose concentration was obtained in the range of 2.5x10-5 mol/L to 2.7~10-3 mol/L with a detection limit of 10 I~mol/L （S/N=3）. The sensor also exhibits long-term stability, good reproducibility and good anti-interference ability |
