Non-competitive reversible inhibition of laccase by H<inf>2</inf>O<inf>2</inf> in osmium mediated layer-by-layer multilayer O<inf>2</inf> biocathodes
A systematic study of the inhibition of laccase by hydrogen peroxide in oxygen biocathodes composed of layer-by-layer selfassembled multilayers of Trametes-trogii laccase and osmium derivatized poly(allylamine) redox mediator has been accomplished using a rotating disc electrode at different electro...
