The graphene have been widely explored as supporting materials for decoration of noble-metal nanoparticles (NPs) owing to a large surface area, excellent mechanical and chemical properties. However, there are insufficient nucleation sites on graphene sheets for growth of metal NPs, which results in low loading metal NPs. Recently, several attempts have been developed to achieve high loading NPs on graphene sheets for various applications. Herein, we demonstrated the functionalization of graphene sheets (G) with ionic liquid (IL) (f-graphene) and preparation of gold (Au) NP/f-graphene nanohybrids for glucose biosensor. The morphology of Au NP/f-graphene was investigated by TEM imaging. The electrochemical properties of Au NP/f-graphene were characterized by cyclic voltammetry and amperometry measurements.
