DEVELOPMENT OF A NON-ENZYMATIC BIOSENSOR BASED ON ZnO/Pd NANOPARTICLES FOR GLUCOSE DETECTION

Abstract

In this study, a ZnO/Pd nanocomposite material was synthesized via a hydrothermal method for application in non-enzymatic glucose biosensors. The morphology and crystalline structure of the synthesized material were characterized using field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and energy dispersive X-ray spectroscopy (EDS). The resulting ZnO/Pd nanocomposite was subsequently employed in the fabrication of a nonenzymatic glucose biosensor, which exhibited a high sensitivity of 1.8µA·mM⁻¹ and a detection limit of 1.0mM. These results highlight the promising potential of ZnO/Pd nanocomposites in the development of non-enzymatic glucose sensors in particular, and biosensors in general.
