Glucose sensor has used enzyme to measure the concentration of glucose in the human blood. However, the glucose sensor has a problem with enzyme stability because the activity is changed according to various conditions such as pH, temperature and humidity. To solve this problem, the modified electrode measured glucose using nickel oxide without enzyme. The modified electrode was deposited more nickel oxide on the ITO/polydopamine(PDA) surface using functional group of PDA to form coordinate covalent bond with nickel oxide. We checked the electrode surface by using Electrochemical Impedance Spectroscopy (EIS), Field Emission Scanning Electron Microscope (FE-SEM) and Energy Dispersive X-ray Spectroscopy (EDX). Using cyclic voltammetry (CV), we confirmed the electrochemical reactions. As a result we studied that the modified electrode was shown possibility to use the glucose sensor.
