An electrochemical approach to determine protein concentration, based on affinity of silver ion to protein was examined. A solid silver electrode was oxidized and reduced in PBS solution containing bovine serum albumin, BSA. Electrochemically generated silver ions produce AgCl or a complex with BSA. Reduction of AgCl and Ag-protein complex proceed at different potential which enables determination...
Bioelectrocatalytic reduction of oxygen to water at electrodes modified with gold nanoparticles and a new laccase from Trichaptum abietinum (TaLc) was studied. The bioelectrocatalytic current was found to be much higher at TaLc modified electrodes than at similarly prepared electrodes modified with a broadly used laccase from Trametes hirsuta (ThLc). To explain this difference the bioelectrocatalysis...
