A novel enzymatic bioelectrode system combining a redox hydrogel with a carbon NanoWeb

A novel bioelectrode system has been prepared in which an enzyme and a conducting polymerhydrogel are combined in a nanostructured scaffold. The latter consists of fibres of carbonNanoWeb, grown by chemical vapour deposition onto reticulated vitreous carbon (RVC). Thecatalytic currents produced by this new bioelectrode system are significantly larger than those obtained using conventional electrodes.
