Grafen Oksit-Polianilin Nanokompozit Temelli Amperometrik Glukoz Biyosensörü Geliştirilmesi.

In this study, Pt electrode was modified with graphene oxide-polyaniline (GO-PANI) nanocomposite and used in the fabrication of amperometric glucose biosensor. Glucose oxidase (GOD) was immobilized on the modified Pt electrode by using a cross-linking agent. The proposed Pt/GO-PANI/GOD biosensor exhibited a sensitivity value of 36.11 μA mM-1 cm-2 with a linear range of 0.59-9.15 mM and the detection limit of 0.24 mM under optimum conditions. The interference effects of ascorbic acid (AA) and uric acid (UA) on the developed glucose biosensor were studied, and it was observed that the biosensor was highly selective to glucose.
