In this communication, 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) funtionalized graphene nanoribbons (HP-beta-CD/GNRs) were prepared for the first time by using a simple wet chemical strategy, and then, the HP-beta-CD/GNRs were applied for constructing electrochemical sensors for three representative analytes (p-aminophenol, p-AP; L-tyrosine, Tyr; rhodamine B, RhB). Owing to the synergetic effects of GNRs (excellent electrochemical properties and large surface area) and HP-beta-CD (high host-guest recognition and enrichment capability), the highly sensitive electrochemical sensing platforms of three analytes were established by using HP-beta-CD/GNRs modified electrode, and the detection limits were 0.0008, 0.003, and 0.001 mu M for p-AP, Tyr, and RhB, respectively.
