چکیده
Here we report on the design and study of a biofuel cell consisting of a glucose oxidase-based anode (Aspergillus niger) and a laccasebased cathode (Trametes versicolor) using osmium-based redox polymers as mediators of the biocatalysts’ electron transfer at graphite electrode surfaces. The graphite electrodes of the device are modified with the deposition and immobilization of the appropriate enzyme and the osmium redox polymer mediator.

Glucose/O(2) biofuel cells (BFCs) with an improved power density and stability were developed, using glucose oxidase (GOD) nanotubes with polypyrrole (PPy)-carbon nanotubes (CNTs)-GOD layers deposited on their surface as an anode and a PPy-laccase-2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonate) diammonium salt (ABTS) film type cathode. The GOD nanotubes were fabricated within the nanopores o...
متن کاملMediatorless high-power glucose biofuel cells based on compressed carbon nanotube-enzyme electrodes
Enzymatic fuel cells use enzymes to produce energy from bioavailable substrates. However, such biofuel cells are limited by the difficult electrical wiring of enzymes to the electrode. Here we show the efficient wiring of enzymes in a conductive pure carbon nanotube matrix for the fabrication of a glucose biofuel cell (GBFC). Glucose oxidase and laccase were respectively incorporated in carbon ...
