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 in 20 mM glucose. The coverage of enzyme on 0.07 cm area of electrode modified with CHI@rGO-PAni/Frt was calculated to be 3.80 × 10 mol cm.
一种固定在壳聚糖（CHI）@还原氧化石墨烯（rGO）-聚苯胺（PAni）/铁蛋白（Frt）/葡萄糖氧化酶（GOx）上的玻碳电极（GC）生物电极已经制备。通过循环伏安法（CV）、线性扫描伏安法（LSV）和电化学阻抗谱（EIS）技术对制备的电极进行了表征。通过扫描电子显微镜（SEM）和傅里叶变换红外（FTIR）光谱对其进行了形态学表征。该生物电极在 20mM 葡萄糖中提供了 3.5±0.02 mAcm 的稳定电流响应。通过计算，在面积为 0.07cm 的电极上，CHI@rGO-PAni/Frt 修饰物上的酶覆盖率为 3.80×10molcm。
