Fabrication of Glucose Biosensor Based on Poly（thionine） Modified on the Screen-printed Electrode
摘要
Abstract
ABSTRACT A novel electrochemical enzyme biosensor for determintion of glucose in food was developed by poly （Thionine） and glucose oxidase on the Screen-printed electrode by chitosan organic and inorganic sol-gel. The bio- sensor shows fast response, high sensitivity and good stability. In addition, the biosensor operated at low potential would be interference free from aseorbic acid, citric acid, sodium benzoate, sucrose, fructose. Under optimal experimental co,lditions, The linear response of the sensor to glucose was in the concentration range of 5.2 × 10^-5 - 2.5 × 10^-3 mol/L with a detection limit of 4.96 × 10^-6 mol/L.关键词
