Research on Glucose Oxidase Biosensor Based on Reverse Iontophoresis

Abstract:

Objective: Making a glucose sensor to detect the glucose which is extracted from the tissue fluid on reverse iontophoresis. Method: In the role of the catalysis of glucose oxidase which was fixed in polyethylene oxide gel, the glucose and potassium ferricyanide were change into gluconic acid and potassium ferrocyanide. Then we could get the concentration of glucose by detecting the current which was created by the redox reaction. Results: The glucose sensors could detect the concentration of glucose in the range of 2.2~22mmol/l and have a good linear too. The conformance test results show that the deviation of multiple measurements of the same sensor is less than 2% and the reaction time is less than 1s. Conclusion: The sensors could detect the blood glucose.
