Immobilization of glucose oxidase on carbon paper electrodes modified with conducting polymer and its application to a glucose fuel cell

Fabrication and Characterization of Glucose Fuel Cells with a Microchannel Fabricated on Flexible Polyimide Film

“…The catalytic oxidation of glucose can be clearly seen at potentials higher than 0.12 V. The maximum current density was 1457 μA/cm 2 . This superior performance was due to the promotion of oxidation reactions by GOD and fast electron transfer by the mediator osmium complex [23,24]. The high current density saturated at a potential about 0.2 V and then showed a decrease from about 0.3 V. In this experiment, it is presumed that the reduction of the current density was due to the removal of the GOD/osmium complex mediator from the anode and the exhaustion of glucose near the surface of anode.…”

Rectangular flake-like mesoporous NiCo2O4 as enzyme mimic for glucose biosensing and biofuel cell

“…Research findings demonstrate that enzymatic catalysts exhibit high activity and excellent selectivity, but the unstable operating environment and fragile stability greatly hinder their practical applications [5,6]. To overcome these drawbacks, non-enzymatic catalysts (such as precious metal nanoparticles or alloys [7][8][9][10], composite materials [11,12], polymers [13,14] and transition metal oxides [15][16][17][18]) as enzyme mimics show higher performance than enzymatic ones. Among these non-enzymatic catalysts, transition metal oxides play important roles due to their high intrinsic catalytic performances, low cost, and environmental friendliness.…”

Modified gold surfaces by 6-(ferrocenyl)hexanethiol/dendrimer/gold nanoparticles as a platform for the mediated biosensing applications

“…However, the thick protein layer surrounding flavin redox centre results in difficulties on direct electron transfer between FAD and electrodes [2,3]. It has taken about half a century and tremendous amount of research to overcome this problem and to obtain better electron transfer between the enzyme and electrodes such as adding redox mediators [4], conducting polymers [5], nanoparticles [6] and dendrimers [7]. The surface quality is an important factor affecting results obtained with electrochemical methods especially when self assembled monolayers (SAMs) are applied to build a recognition layer with various functional groups.…”
