Enzyme biosensor based on urea treated on the activated carbon fiber electrode prepared by thermal solid-state reaction |
| 초록 |
The performance of enzyme-based electrode was increased by addition of nitrogen groups on activated carbon fiber from urea treatment. The nitrogen groups had properties of good conductivity and hydrophilicity which increased the performance of the electrode such as the value of current and sensitivity. The carbon fiber was activated by KOH for improving adsorption of glucose oxidase (GO) enzyme and introducing oxygen and nitrogen functional groups which were reacted with urea. The reactions were carried out various weight ratios of amounts of urea per activated carbon fiber (3:1, 5:1, 8:1) at 200 OC. The synthesized samples were characterized by X-ray photoelectron spectroscopy to analysis chemical elements composition on the surface. Glucose sensing was carried out by cyclic voltammetry (CV) and amperometric methods. The mechanism of the sensitive on enzyme activity in the electrodes of glucose sensor was modeled by enzyme kinetics using the Michaelis-Menten equation. |
