摘要：

A rapid and simple method for the preparation of a miniature glucose sensor (enzyme electrode) has been developed. Glucose oxidase is immobilized by glutaraldehyde in albumin gel on a cellulose diacetate membrane. This membrane is directly attached to an H2O2 detecting electrode and covered with an external polyvinyl chloride membrane. The response time of the glucose electrode thus prepared is about 2 min, the calibration graph is linear for 0-30 mM glucose, and the sensor can be used repeatedly at room temperature for at least 10 days with small deterioration in response.
