Screen printed carbon electrodes(SPCEs) is widely known as electrochemical reaction sensing platforms due to their simple fabrication in terms of compositions and relatively low cost of production. The Poly(acryl amide)-Poly(vinyl imidazole)(PAA-PVI)-osmium complex mediator was employed onto SPCEs with glucose dehydrogenase (GDH), which is to oxidase the glucose. The different molecular weight in redox polymer was controlled by initiator and catalyst, and then it was identified by gel permiation chromatography (GPC). The PAA-PVI-osmium complexes were synthesized by the coordinating pyridine group having different functional group at 4-position with osmium compounds. The electrochemical catalytic reaction effect depending on molecular weight was measured by cyclic voltammetry with modified SPCEs. The electrical currents by the different molecular weight were shown with a good linear response with glucose concentrations with GDH. These results can help to develop in the medical diagnosis field and electrochemical biosensor.
