Protein film voltammetry (PFV) has been demonstrated in order to evaluate ET and catalytic properties of MCO directly on the electrode surface. In this approaeh, the electrode and redox centers of the enzyme are considered to be a donor-acceptor pair. The electrode donates or accepts electrons over a continuous range of potentials, and current is used as an indicator of the movement of electrons within the enzyme [36-39].
