NOVELTY - An electrically reduced graphene oxide-gold nanorods/poly(2,6-pyridine) dicarboxylic acid complex comprises a gold nanorod composite material stably binding with graphene oxide as a support matrix on surface of a poly(2,6-pyridinedicarboxylic acid) electropolymerized film. USE - Electrically reduced graphene oxide-gold nanorods/poly(2,6-pyridine) dicarboxylic acid complex for determining adenine and guanine. ADVANTAGE - The electrically reduced graphene oxide-gold nanorods/poly(2,6-pyridine) dicarboxylic acid complex has very high electrocatalytic activity for the oxidation of guanine and adenine bases. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing an electroreduction of graphene oxide-gold nanorods/poly(2,6-pyridine) dicarboxylic acid complex, which involves reducing chloroauric acid in an ice bath of sodium borohydride to obtain a gold seed solution, reducing chloroauric acid with ascorbic acid and growing a reduced gold component slowly on surface of the gold species to obtain a gold nanorod, adding the gold nanorods to an aqueous solution of graphene oxide through electrostatic interaction, adsorbing electrostatically gold nanorods on the surface of graphene oxide and separating to obtain a graphene oxide-gold nanorod composite, taking 2,6-pyridinedicarboxylic acid as a polymerization liquid, using cyclic voltammetry, and cyclic scanning, polymerizing film on the electrode surface to obtain a poly(2,6-pyridine)dicarboxylic acid film, fixing the graphene oxide-gold nanorod composite on the surface of the poly(2,6-pyridine)dicarboxylic acid film in electrolyte, using constant potential method and reducing graphene oxide to obtain the finished product.
