Biofuel cell is an electrochemical device that converts chemical energy into electrical using enzymes as catalysts and simple, natural substances e.g. glucose as fuel. [1,2,3] Here, the glassy carbon (GC) and graphite electrodes were modified with laccase from Cerrena unicolor bonded to single-walled carbon nanotubes (SWCNTs) via various linking groups or cross-linked with bovine serum albumin (BSA) by glutaric aldehyde. Anode was composed of glassy carbon electrode, modified with SWCNTs and liquid crystalline cubic phase, containing glucose dehydrogenase. The anode described and GC electrode, decorated with SWCNTs with covalently bound laccase as cathode were successfully used to construct the biofuel cell. The parameters of the cell were evaluated.
