Polyaniline-silver (PANI-Ag)/ferritin (Frt)/glucose oxidase (GOx) biocompatible anode was utilized for creating power from glucose. The synthesized nanocomposite was investigated by EIS (Electrochemical impedance spectroscopy), XRD (X-ray diffraction), FTIR (Fourier transform infrared spectroscopy), SEM (Scanning electron microscopy), CV (Cyclic voltammetry), and LSV (Linear sweep voltammetry) to know the morphology, crystallinity and electrochemical behaviour of the nanocomposite. The electroactive support (PANI-Ag) was utilized for the immobilization of the enzyme (GOx) and a biocompatible mediator (Frt) to enhance the electrical signals. The electrochemical estimations of the manufactured bioanode were done by utilizing cyclic voltammetry (CV) and linear sweep voltammetry (LSV). The current density obtained by the PANI-Ag/Frt/GOx bioanode was observed to be 25.40 ± 2 mA cm at 40 mM of glucose concentration at a scan rate of 100 mVs.
聚苯胺-银（PANI-Ag）/铁蛋白（Frt）/葡萄糖氧化酶（GOx）生物相容性阳极被用于从葡萄糖中产生电能。通过电化学阻抗谱（EIS）、X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、循环伏安法（CV）和线性扫描伏安法（LSV）对合成的纳米复合材料进行了研究，以了解其形态、结晶度和电化学行为。电活性载体（PANI-Ag）用于固定酶（GOx）和生物相容性介质（Frt），以增强电信号。通过循环伏安法（CV）和线性扫描伏安法（LSV）对制备的生物阳极进行了电化学评估。在扫描速率为100 mVs、葡萄糖浓度为40 mM时，PANI-Ag/Frt/GOx生物阳极获得的电流密度为25.40±2 mA/cm。
