▎ 摘　　要

High dispersion of Pt nanoparticles on polymeric ionic liquid-functionalized graphene sheets is achieved through a sonochemical-assisted method. As-synthesized nanohybrids are characterized by X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and X-ray diffraction (XRD) measurements. The employment of polymeric ionic liquids provides amount of specific binding sites to anchor and grow Pt nanoparticles with a uniform size and position on a graphene surface. The electrochemical performance of the resultant nanohybrid-based biosensor devices is tested for detection of glucose molecules, showing high sensitivity and low detection limit.
