Abstract

Brilliant green (BG), which belongs to the triphenylmethane family, has been electrochemically polymerised by cyclic voltammetry on bare carbon film electrodes (CFE) and for the first time on carbon nanotubes (CNTs) and poly(3,4-ethylenedioxythiophene) (PEDOT) modified CFE. The modified electrodes have been characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in order to establish the position importance and the individual role of each component (CNT, PEDOT and PBG) in the overall electrode performance. The analytical performances of different electrode architectures towards hydrogen peroxide detection allowed the choice of the best electrode configuration for further application of the newly developed electrodes for sensor and biosensor construction.
