Abstract:
The Poly(3,4-ethylenedioxythiophene) graphene ( PEDOT-rGO) composite film was prepared by one step pulse potentiostatic method, based on the π-π* interaction and the polymerization reaction of hydrogen bond between the graphene ( rGO) and the aromatic ring of 3,4-ethylenedioxythiophene ( EDOT) monomer. Then the nickel nanoparticles ( NiNPs ) were electrodeposited on composite film to obtain a composite film-modified glassy carbon electrode ( NiNPs/PEDOT-rGO/GCE ) . The catalytic performance of NiNPs/PEDOT-rGO/GCE towards the oxidation of glucose was studied by electrochemical method. The experimental results showed that the NiNPs/PEDOT-rGO/GCE could be used as a nonenzyematic sensor for detection of glucose. This method had high stability, good selectivity, wide linear range ( 2 μmol/L-58 mmol/L) and low detection limit (0. 7 μmol/L), realizing the rapid and sensitive detection of glucose.
