Abstract
A wide range of carbon nanofiber (CNF) mats with controlled properties of fiber diameter, surface area, porosity, and conductivity were fabricated via a facile and economical electrospinning method. CNFs are used as supports for bioelectrodes to enhance enzyme utilization. This study employed glucose oxidase (GOx) in a redox hydrogel system, which mediates electron transfer via osmium metal center, to create a glucose bioelectrode. CNFs reduces the hydrogel thickness and enhances the electron transport. CNFs exhibit promising glucose oxidation current density reaching 10 mA cm−2 that is higher than those of commercial carbon materials such as multiwalled carbon nanotubes (MWCNT), Bucky paper, Pyrograf, and Toray paper.
