A metallacarborane redox mediator for an enzyme-immobilized chitosan-modified bioanode

Bioelectrochemistry, 2010
We describe here the first report of a metallacarborane complex as a redox mediator in a functioning biofuel cell. Specifically, we have prepared a water-soluble salt of the complex anion [commo-3,3'-Fe-(closo-2,1-C(2)B(9)H(11))(2)](-) and employed it as a redox mediator for glucose oxidation using chitosan/multiwalled carbon nanotube-modified ...

A high performance nanocomposite based bioanode for biofuel cell and biosensor application

Analytical Biochemistry, 2021
Herein, to improve the current density and sensitivity for biofuel cell and glucose sensing application, a bioanode based on redox polymer (PEI-Fc) binding polydopamine (PDA) coated MWCNTs (PEI-Fc/PDA/MWCNTs) nanocomposite and glucose oxidase (GOD) was fabricated.

Substrate and electrode potential affect electrotrophic activity of inverted bioanodes

Bioelectrochemistry, 2016
Electricity-consuming microbial communities can serve as biocathodic catalysts in microbial electrochemical technologies. Initiating their functionality, however, remains a challenge. One promising approach is the polarity inversion of bioanodes. The objective of this study was to examine the impact of bioanode substrate and electrode potentials on ...

On the nature of the electrochemical response in mediated bioanodes with yeast cells

Bioelectrochemistry
Herein, the electrochemical responses of Saccharomyces cerevisiae cultivated in YPD medium were tested in amperometric mode using microanalytical screen-printed electrodes modified with potassium ferricyanide and 1,10-phenanthroline-5,6-dione as mediators. The electrochemical signals obtained correlated well with the yeast growth curve. Electrochemical

Conductive Carbon Nanotube Hydrogel as a Bioanode for Enhanced Microbial Electrocatalysis

ACS Applied Materials & Interfaces, 2014
Enhancing microbial electrocatalysis through new material design is essential to the efficient and stable operation of bio-electrochemical system (BES). In this work, a novel conductive carbon nanotube (CNT) hydrogel was fabricated by electrodepositing both CNT and chitosan onto a carbon paper electrode and used as a BES anode electrode.

Composition Dependence of Glucose Oxidation at Mediated Glucose Oxidase Bioanodes

ECS Meeting Abstracts, 2013
In mediated enzyme electrodes, electrons are transferred between the enzyme and electrode surface via a redox species [1]. Previous studies have documented the parameters affecting mediated GOx electrodes and the effect of the composition, mediator structure, pH etc [2].

Effects of Carbon Nanotube Paper Properties on Enzymatic Bioanodes

Electroanalysis, 2013
AbstractCarbon papers are frequent current collectors in fuel cells, but recently carbon nanotube papers have been introduced as new types of carbon paper. They have varying thickness, surface area, density, gas permeability, and conductivity. This paper studies the effect of these properties on electrochemical performance.

Bioanode engineering for living solar cells

Whole-cell biophotovoltaic (BPV) devices leverage photoautotrophic microorganisms like cyanobacteria to convert sunlight and water into bioelectricity. They are capable of growing on sequestered carbon dioxide (CO2), eliminating the need to add exogenous organic carbon.

(Keynote) Utilizing Bioengineering for Fabricating Catalytic Cascade Bioanodes

ECS Meeting Abstracts, 2016
Over the last decade, there have been major developments in materials engineering for bioelectrodes (i.e. bioanodes and biocathodes in biofuel cells and biosensors), including the engineering of nanomaterials and nanostructured electrodes for increasing electrochemically active surface areas and increasing the rate of direct electron transfer. However,
