摘要：
The effects of introducing gold (Au) nanoparticles (NP) on the electrochemical properties of graphene functionalized with ionic liquid were investigated by cyclic voltammetry, amperometry, and AC impedance analysis. The introduction of Au NPs onto graphene-ionic liquid sheets led to enhanced electron transfer rate, low charge transfer resistance, and large electrocatalytic area. An electrochemical biosensor device based on the hybrid of Au NPs and functionalized graphenes was fabricated and found to have superior electrochemical performance in the detection of glucose, with a sensitivity of 0.16 mu A mM(-1), a detection limit of 0.13 mM, and a response time of 5 s.
