Hydrogen Peroxide Detection Using Prussian Blue?modified 3D Pyrolytic Carbon Microelectrodes

A highly sensitive amperometric Prussian blue-based hydrogen peroxide sensor was developed using 3D pyrolytic carbon microelectrodes. printed multielectrode electrochemical cell enabled simultaneous reproducible blue modification on multiple electrodes. The effect of oxygen plasma pre-treatment and deposition time electrodeposition studied. response 2D sensors to the addition in ?M sub-?M concentrations phosphate buffer investigated. high sensitivity comparable flow injection systems a detection limit 0.16 demonstrated with microelectrodes at stirred batch condition
