Amperometric glucose sensors based on ferrocene containing polymeric electron transfer systems-a preliminary report.
In this paper we introduce a preliminary work in which a redox mediator containing polyvinylferrocene immobilized on silica gel particles is synthesized. Carbon paste electrodes prepared with this polymeric mediator were studied for their stability in aqueous media for a month. The results indicated that approximately 70% of the initial activity was retained after a month. A steady state amperometric measurement of this carbon paste electrode containing this mediator and glucose oxidase at different potentials showed a linear relationship at elevated glucose concentration.
