Optimization of Glucose Powered Biofuel Cell Anode Developed by Polyaniline-Silver as Electron Transfer Enhancer and Ferritin as Biocompatible Redox Mediator

Abstract

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−2 at 40 mM of glucose concentration at a scan rate of 100 mVs−1.

Polythiophene/multiwalled carbon nanotubes/nitrate reductase deposited glassy carbon electrode (GCE/PTH/MWCNT/NR): a novel biosensor for the detection of nitrate in aqueous solution

“…It has been observed that redox peak current is in directly proportional to the scan rate which suggests that the nitrate reduction by the GCE/PTH/MWCNT modified bioelectrode is dominated by a surface controlled phenomenon. Hence, it can be deduced from the results that scan rate has a significant effect on the electrochemical behavior of which includes a mixture of adsorption and diffusion controlled processes (Haque et al 2017(Haque et al , 2018Perveen et al 2017Perveen et al , 2018b.

A comprehensive review of current research on various materials used for developing composite bipolar plates in polymer electrolyte membrane fuel cells

“…Moreover, they are also searching for an energy source to reduce environmental pollution and fossil fuel dependency. [ 1 ] Renewable energy sources like solar, wind, geothermal and biomass energy lack consistency in supply. Due to mobility issues, there is limited application of this energy in automobiles and remote areas.…”

Development of Cd (II) Ion Probe Based on Novel Polyaniline-Multiwalled Carbon Nanotube-3-aminopropyltriethoxylsilane Composite

“…A lot of study is conducting on composite meterials for different applications because of high increase properties after making composite by involving individual initiators quality too [18][19][20][21][22][23][24][25][26][27][28]. Therefore, to improve the current response towards Cd 2+ concentration, especially in terms of response stability, we explored a conducting polymer-based composite-coated electrode material.…”
