▎ 摘　　要

The detection of glucose plays a vital role in clinical, biological, and environmental studies. The present work used a facile wet chemical route for the preparation of beta-cyclodextrin-functionalized reduced graphene oxide (beta-CD/RGO), which was then investigated using Raman spectroscopy, UV-Vis spectroscopy, and FTIR spectroscopy. The corresponding results provided evidence for the effective coverage of beta-CD on the surface of RGO. The beta-CD/RGO-coated glassy carbon electrode (GCE) showed a low limit of detection (LOD) of 0.4 mu M, and the linear range was as wide as 1 mu M - 8 mM. In addition, the successful application of the developed electrochemical biosensor for sensing glucose in blood specimens has been realized.
