▎ 摘  要

A glassy carbon electrode (GC) immobilized with chitosan (CHI)@reduced graphene (rGO)-polyaniline (PAni)/ferritin (Frt)/glucose oxidase (GOx) bioelectrode was prepared. The prepared electrode was characterized by using cyclic voltammetry (CV), linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS) techniques. The morphological characterization was made by scanning electron microsopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. This bioelectrode provided a stable current response of 3.5 +/- 0.02 mAcm(-2) in 20mM glucose. The coverage of enzyme on 0.07cm(2) area of electrode modified with CHI@rGO-PAni/Frt was calculated to be 3.80x10(-8)molcm(-2).
