Abstract

Glucose oxidase (b-D-glucose: oxygen 1-oxidoreductase; EC 1.1.3.4) is a flavoprotein which catalyzes the oxidation of b -D-glucose to D-glucono-d-lactone and H2O2 using molecular oxygen as an electron acceptor. GLUCOSE OXIDASE (GOx) has important applications in several different industries. One of its new applications is in biofuel cell (BFC) industry. Biofuel cell is a bio-electronic device which convert biochemical energy into electrical energy using a BIOCATALYST. Enzymatic biofuel cell uses enzymes, for example GLUCOSE OXIDASE as a BIOCATALYST to produce electrical energy. In this study, we report the fabrication and characterization of a carbone nanotube (CNT)-based sugar/oxygen BFC operating in phosphate buffer. GOx as anodic bioelement, was immobilized on carbon fiber electrode modified with CNT and nafion. For this purpose, first, 2 mg/ml GOx enzyme solution was prepared in 200 ml potassium phosphate buffer pH=7.4. Second 100 ml of MWCNT solution was mixed with 100 ml GLUCOSE OXIDASE enzyme and was dropped on carbon fiber. Then 100 ml nafion was added as a thin layer on the electrode. The GOx/CNT-based bioanode and one air-cathode were combined into a functional BFC and the function of BFC was carefully investigated. After 150 min of injection of glucose solution in cell, the current was 700 mA at 490 mV. Results of fabricated cell show that presented enzymatic BFC can be used as a power source to generate electricity for implantable and portable miniature devices.
