  • Electropolymerizable film, and method of making and use thereof
    Patent number: 6180346
    Abstract: An electrode and method of preparing an electrode by electropolymerizing a film on the conductive working surface of an electrode. The electrode is modified by reductive electropolymerization of a thin film of poly[Ru(vbpy)32+] or poly[Ru(vbpy)32+/vba] (vbpy=4-vinyl-4′methyl-2,2′-bipyridine and vba=p-vinylbenzoic acid) and the electrode is used for the electrochemical detection of aqueous GMP, poly[G], and surface immobilized single-stranded DNA probes. The film is formed from a co-polymer of a mediator such as Ru(vbpy)32+ and a functionalized moiety having a carboxylate group such as p-vinylbenzoic acid. A DNA probe is attached covalently to the carboxylate group via a carbodiimide reaction followed by amidation of an amino-linked single-stranded DNA.
