Abstract

A strategy was established for the synthesis of redox electrodepo¬sition polymers (redox EDP) consisting of the synthesis of monomers with attached imidazolyl anchor groups, followed by radical copolymerization with a variety of monomers bearing side chains with different steric, hydrophobic, and electronic properties. The synthesized EDP were coordinatively modified by reaction with Os-bis-N,N'-(2,2'-bipyridyl)-dichloro complexes. The obtained redox-EDPs were precipitated on Pt electrodes by means of an electrochemically induced pH modulation in the presence of a pyrrolo¬quinoline quinone-dependent glucose dehydrogenase (PQQ-sGDH). The impact of the redox-EDPs composition on the electron transfer properties of the resulting reagentless glucose biosensors was investigated.
