A biofuel cell is a device for converting chemical energy to electrical energy by a simple way. A high-impact anode is prepared in this research. Here, carboxylated multiwall carbon nanotube (COOH-MWCNT), polydiallyldimethyl ammonium chloride (PDDA) and alcohol dehydrogenase were cast on modified glassy carbon with polymethylene green to construct the bioanode for ...

Nanotechnology has opened up new opportunities for the design of nanoscale electronic devices suitable for developing high-performance biofuel cells. Glucose-based biofuel cells as green energy sources can be a powerful tool in the service of small-scale power source technology as it provides a latent potential to supply power for various implantable medical electronic devices. By using physiol...

Enzyme-based biofuel cells (EBFCs) are systems that use a variety of organic compounds to produce electricity through oxido-reductase enzymes, such as oxidase or dehydrogenase as biocatalysts immobilized on electrodes. In this study, a single-chamber EBFC consisting of carbon electrodes that operating at ambient temperature in phosphate buffer, pH 7 is reported. The EBFC anode was based on gluc...

One of the key goals of enzymatic biofuel cells research has been the development of a fully enzymatic biofuel cell that operates under a continuous flow-through regime. Here, we present our work on achieving this task. Two NAD(+)-dependent dehydrogenase enzymes; malate dehydrogenase (MDH) and alcohol dehydrogenase (ADH) were independently coupled with poly-methylene green (poly-MG) catalyst fo...

The enzyme-based keypad lock was integrated with a biofuel cell yielding a self-powered biomolecular information security system. The correct "password" introduced into the keypad lock resulted in the activation of the biofuel cell, while all other "wrong" permutations of the enzyme inputs preserved the "OFF" state of the biofuel cell.

A novel paper-based biofuel cell with a series/parallel array structure has been fabricated, in which the cell voltage and output power can easily be adjusted as required by printing. The output of the fabricated 4-series/4-parallel biofuel cell reached 0.97±0.02 mW at 1.4 V, which is the highest output power reported to date for a paper-based biofuel cell. This work contributes to the developm...
