Abstract
Flexible carbon fiber electrodes (FCFs) are promising platforms for the fabrication of enzymatic bioelectrodes, mainly because their surfaces improve the direct electron transfer (DET) from redox enzymes. Recently, we introduced new concepts in intravenous implantable bioelectronics based on FCF and special efforts have concentrated on the development of enzyme-based electrodes for biosensors and biofuel cells. In this review, some of our results will be presented as well as the most important properties of FCFs will be discussed with the goal of developing new bioelectrochemical models for understanding the interface between bio-systems (e.g., enzymes and yeasts) and an FCF surface. Moreover, we focus on the strategic use of a modified FCF for the miniaturization of enzymatic biofuel cells to supply power to bionic implants, such as in vivo biosensors and biofuel cells.
