Abstract
A bioanode of polyaniline (PANI) and polystyrene modified with redox enzyme glucose oxidase was fabricated by using electrospinning. The bioanode was prepared by depositing the electrospun fibers over a glassy carbon electrode (GCE). The bioanode composite was characterized by FTIR (Fourier transform infrared spectroscopy), TGA (Thermogravimetric analysis), XRD (X-ray diffraction), SEM (Scanning electron microscopy), and HR-SEM (High resonance scanning electron microscopy). The electrochemical characteristics of the fibrous anode are studied by cyclic voltammetry (CV), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS). The maximum current density provided by the GCE/PANI-polystyrene/GOx nanofibers was 2.689 mA cm−2 in the presence of 20 mM glucose, indicating the successful glucose-sensing ability of the GOx-modified anode. The mentioned bioanode showed significant operational stability. Fabricating fibrous matrix opens a gateway to explore its possible exploitation in wearable and miniatured EBFCs for future research.
