Glucose amperometric sensor used mediators for electron-transfer between electrodes and enzymes. Complexes of the group VIII metals iron (II), ruthenium (II) and osmium (II) have been synthesized and characterized electrochemically with respect to their ability to act as electron-transfer mediators for redox enzymes. We used FAD glucose dehydrogenase (FAD-GDH) as redox enzyme to selectively measure glucose. FAD-GDH was less activity than GOx and did not react well with cationic mediators. But we have developed Polyvinylimidazole complex of [Ru(dam-bpy)2Cl]+/2+ that is cation and reacts well through different glucose concentration at 0-20mM in 1X PBS. We checked characterization of chemical structure with 1H-NMR, FT-IR, UV-VIS, CV and electrochemical properties with CV, multi-potential step. Finally, we studied cationic ruthenium mediator for application of glucose sensor using FAD-GDH.
