<p>Thin films of transition metal complex-based redox polymers (94) are electrodeposited on electrodes (90) via application of fixed or cycled potential. When hydrated, an electrodeposited film conducts electrons by electron exchange between backbone-bound, but mobile, functional segments of its redox polymer constituents. These functional segments, or redox complexes, have labile ligands, such as chloride anions, for example, in their coordinating spheres. The backbones of the redox polymers have strongly coordinating ligands, such as pyridine- or imidazole-containing functions, for example, which are generally not coordinated prior to deposition. Electrodeposition results from coordinative crosslinking by exchange of labile ligands and strongly coordinating ligands between polymer chains, provided sufficient functional segments of the redox polymers are present at the electrode surface. When a biological macromolecule or protein (98), such as redox enzyme, is added to the solution from which the redox polymer is electrodeposited, it is co-electrodeposited on the electrode surface.</p> |
