| This work presents an effective bioelectrochemical system for the electrocatalytic reduction of hydrogen and organic peroxides. The nanostructures can improve the interface between biomolecules and the electronic transducer, because these reduced distance between the redox center of proteins and the electrode. Also provide a three-dimensional structure similar to the microenvironment of redox proteins in biological systems. Gold nanoparticles have been electrochemically deposited on a Pt electrode previously modified with a polyferrocenyl polycyclosiloxane polymer [1] as base, in order to carry out the direct electrochemistry of horseradish peroxidase. The enzyme was immobilized covalently in the AuNPs through thiol functional groups which are present in the protein structure. This system showed high activity with an apparent Michaelis-Menten constant lower than the intrinsic one. | |
