Wiring of Glucose Oxidase within a Hydrogel Made with Polyvinyl Imidazole Complexed with (Os-4,4-dimethyl 2,2'-bipyridine)Cl+/2+.

Abstract

Glucose electrodes based c)n hydrogels made by crosslinking glucose oxydise and the redo polymer formed upon complexing polyvinyl imidazole (PVI) with /Os(dmo-bpy)22C1+/2+ (dmo-bpy = 44 dimethoxy-2,2'-bipyridine) on vitreous carbon electrode surfaces were investigated. The redox potential of the hydrogels was -69 mV (SCE) and their glucose electrooxidation current reached a plateau at +50 mV (SCE). Urate and acetaminophen were not electrooxidized at this potential at rates that would interfere with the glucose assays. At 32 mM glucose concentration switching of the atmosphere from argon to 02 reduced the current only by 5%.
