Graphene nanosheets (GS) were prepared through solvent exfoliation, and used to greatly enhance the oxidation activity of rutin. On the surface of GS, a sensitive oxidation wave at 0.26 V was observed for rutin, and the peak currents increased significantly. As a result, a highly sensitive electrochemical method was developed for the determination of rutin. The linear range was from 10 nM to 1.25...
