Abstract
Redox complexes to transport electrodes from biomaterial to electrodes are very important part in com-mercial biosensor industry. A novel osmium redox complex was synthesized by the coordinating pyridine group withosmium metal. A novel osmium complex is described as [Os(dme-bpy)2(ap-im)Cl]+/2+. We have been studied the elec-trochemical characteristics of this osmium complex with electrochemical techniques such as cyclic voltammetry andchronoamperommetry. In order to immobilize osmium redox complexes on the electrode, we deposited gold nano-particles on scren printed carbon electrode(SPE). The electrical signal converts the osmium redox films into an elec-trocatalyst for glucose oxidation.The catalytic currents were monitored that the catalytic currents were linearlyincreased from 1 mM to 5 mM concentrations of glucose.
