Evaluation of the Oxo-bridged Dinuclear Ruthenium Ammine Complex as Redox Mediator in an Electrochemical Biosensor

Writers: Paulo A. Raymundo-Pereira; Ana C. V. Mascarenhas; Marcos F. S. Teixeira Keywords: Biosensor; Electrochemical Abstract: The mediation of electron-transfer by oxo-bridged dinuclear ruthenium ammine [(bpy)2(NH3)RuIII(µ-O)RuIII(NH3)(bpy)2]4+ for the oxidation of glucose was investigated by cyclic voltammetry. These ruthenium (III) […]
