Fabrication of Glucose Oxidase Enzyme Flexible Electrode Based on ZnO Nanorods
Well-aligned ZnO nanorods were grown on the ZnO seed layer coated polyimide (PI) flexible substrate by hydrothermal method and used as supporting matrixes for glucose oxidase (GOx) immobilization. The GOx attached to the surfaces of ZnO nanorods had maintained its biological activity, which improved the direct electron transfer between the active sites and the electrode surface. It will provide a basis for the preparation of flexible glucose biosensors owing to the flexible enzyme electrode showed a sensitive current response. This technique represents a low-cost and simple method for integrating ZnO nanorods into flexible electronic devices and biosensors. The crystal structure and surface morphologies of the as-grown ZnO nanorods were identified by XRD and SEM. UV-Visible and FTIR spectroscopy were used to characterize the glucose oxide chemical structure. PL spectroscopy was used to study optical properties of modified electrode. The electrochemical response to redox of ZnO nanorods modified electrodes was measured by cyclic voltammogram (CV).
