摘要
The IR spectroscopic and electrochemical measurements demonstrated that glucose oxidase (GOx) could be immobilized on the surface of carbon black (CB) using a simple adsorption method. The electrochemical measurements indicated that GOx immobilized on CB could undergo the quasi-reversible and direct electrochemical reaction and keep the bioelectrocatalytic activity for the glucose oxidation. Even after conservation for two weeks, its electrocatalytic activity decreased only 5%, illustrating the good stability of GOx immobilized on CB.
