| Abstract: | Glucose oxidase was attached to the surface of vitreous carbon with different immobilization methods. 1,4-Benzoquinone was used as the mediator to couple the electrochemical with enzymatic reactions, and the kinetic parameters for the enzyme reaction were estimated by using voltammetry and RDE technique. The effects of the immobilization methods were examined on the catalytic activities.current responses and stabilities of the enzyme electrodes. |
