Abstract
The quasi-reversible electron transfer of monoalkylated ferrocenes is characterized by cyclic voltammetry and rotating disc measurements. The examined ferrocene derivatives are identified as suitable fast and reversible mediators for a successful application in amperometric glucose biosensors. The reaction between the mono-alkylferrocenes and glucose oxidase is characterized by high reaction rate constants k 2 in a reaction kinetics of second order. The size of individual molecules (typically 210–650 pm) in acetonitrite and dispersed mediator aggregates (typically 3500–170 000 pm) in aqueous solutions is estimated from diffusion coefficients. The mediators used in an amperometric biosensor system show fast response upon variations in the glucose concentration. A molecular model is proposed for the reaction mechanism.
