An easy compartment-less biofuel cell construction based on the physical co-inclusion of enzyme and mediator redox within pressed graphite discs.
We report on the easy and fast immobilization of glucose oxidase (GOD) and laccase by mech. compression with graphite particles to form disk electrodes. The elec. wiring of GOD and laccase was efficiently carried out by their co-inclusion with ferrocene (Fc) and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonate) diammonium salt (ABTS) resp. A glucose/air compartment-less biofuel cell was constructed based on the assocn. of GOD-ferrocene-graphite disk and laccase-ABTS - graphite disk electrodes as bioanode and biocathode resp. Such biofuel cell yielded a power d. of 23 $μ$W cm-2 at 0.33 V as well as an open-circuit voltage and a short-circuit current of 0.63 V and 166 $μ$A, resp. [on SciFinder(R)]
