摘要
This paper describes a diffusion-controlled electrolysis of glucose with mediated bioelectrocatalysis at microdisk-electrodes. Under conditions of an extremely fast enzyme reaction, compared with the diffusion of glucose, the current in potential-step chronoamperometry reaches an almost steady state within 10 s, and is proportional to the glucose concentration. The current can be detected at +0.1 V (vs. AglAgCl) with 9,10-phenanthrenequinone as a mediator. The addition of carboxymethylcellulose increased the linear range up to 10 mM.
