Abstract
Multi-walled carbon nanotubes wrapped by polyethyleneimine (PEI) and functionalized with a carboxylic acid group (CNT-COOH) were deposited with gold nanoparticles (AuNPs) which has been utilized as a platform to immobilize poly(acriflavine)(PAF) and used as modified electrode (AuNPs/PEI/CNT-COOH/PAF). Electrocatalytic reduction of hydrogen peroxide(H2O2) on the surface of the modified electrode was investigated by cyclic voltammetry and electrochemical impedance spectroscopy (EIS) methods. The cyclic voltammetric results indicated the ability of modified Au electrode to catalyze the reduction of H2O2. AuNPs/PEI/CNT-COOH nanocomposite combined the advantages of PEI, well dispersed CNT-COOH and in situ formed AuNPs, endowed with high stability to the enzyme-free sensor.
