Compared to bare electrodes, it is believed that modified electrodes can reduce overvoltage in many electrode processes, and shows better sensitivity and selectivity, which can be used to distinguish the electroanalytical signals of the solution components. Some mediators have been fixed on the electrode surface by adsorption on the electrode surface and it is a simple method for preparing modified electrodes.
