Abstract |
The layer by layer method [1] become important for preparation of bioelectrocatalytic electrode. However, only recently it was applied to obtain biocathodes potentially applicable in biofuel cell [2, 3]. Our group shown that the nanoparticulate film electrode prepared by layer by layer method combined with sol-gel process exhibits mediated bioelectrocatalysis with laccase dissolved in electrolyte. The electrode modified by film assembled from osmium redox polymer and laccase layers also catalyses dioxygen reduction .
