Abstract
The present invention provides a diabetes biosensor including a porous polymer membrane; two sides of the porous polymer membrane are provided with impermeable membranes; the impermeable membrane on one side is provided with a first electrode, the impermeable membrane on the other side is provided with a second electrode. Specific glucose oxidase is immobilized on the first electrode. In the present invention, the porous polymer membrane has the feature of multiple pores to facilitate the penetration of water and other liquids, and the impermeable membranes on two sides of the porous polymer membrane have the feature of impermeable; the porous polymer membrane, the impermeable membranes, the first electrode, and the second electrode together constitute a sandwich sensor; glucose generates hydrogen peroxide under the action of glucose oxidase; after the hydrogen peroxide generates electron gain and loss on the electrode, an electric signal change is generated and detected by the biosensor; and the biosensor can rapidly measure the blood glucose concentration. In addition, the biosensor can be used as a device for storing drugs, which facilitates the use of the biosensor to inject insulin into a patient with a high blood glucose concentration to control the blood glucose level.
