## Abstract Glucose oxidase (GOD) in SiO~2~ nanoparticle films was cross‐linked by glutaraldehyde (GA), forming GOD‐GA‐SiO~2~ films on the surface of pyrolytic graphite (PG) electrodes. GOD in the GOD‐GA‐SiO~2~ films showed a pair of well defined and quasi‐reversible cyclic voltammetric peaks at −0
## Hydroquinone-adsorbed ghrcose oxidase shows amperometric sensitivities to glucose without assistance of any electron mediator dissolved in glucose solutions. Electrical interaction of the adsorbed hydroquinonesulfonate with the redox center of glucose oxidase is evidenced by quenching of the fl
