Synthesis of the conjugate has been optimised and the conjugates were characterised bio- and electrochemically. Covalent immobilisation of the conjugate on gold electrodes in a dense monolayer results in electrodes with a high binding capacity for biotinylated molecules as well as good electron transfer properties. The application potential of such electrodes for bioelectrochemical systems is demonstrated by electrochemical reduction of hydrogen peroxide under mild conditions catalysed by a bound biotin-microperoxidase MP11 conjugate.
