| Abstract |
Screen printed carbon electrodes (SPCEs) with immobilized osmium-based hydrogel redox polymer, glucose dehydrogenase (GDH) and PEGDGE can be used to apply glucose electrochemical detecting. The osmium redox complexes were synthesized by the coordinating pyridine group having different functional group at 4-position with osmium compounds. The synthesized poly-osmium hydrogel complexes are described as poly(acryl amide)-poly(vinyl imidazole)-[Os(4,4'-disubstituted 2,2'-bipyridines)2Cl]+/2+ (PAA-[Os(4,4'-disubstituted 2,2'-bipyridines)2Cl]+/2+) polymers. The different concentrations of glucose were measured by cyclic voltammetry technique using enzyme-immobilized SPCEs. The resulting electrical currents displayed a good linear response with glucose concentrations with GDH. Therefore, this approach allowed the development of a simple, point of care in the medical field, disposable electrochemical biosensor.
