Recent advances for cyclodextrin-based materials in electrochemical sensing

Owing to the hydrophobic inner cavity and hydrophilic exterior of cyclodextrins (CDs), CDs molecules could exhibit excellent properties in water solubility, molecular recognition and enrichment capability, and CDs-based materials attracted considerable attentions in electrochemical sensing. This review shows the unique advantages and detecting mechanism of electrochemical sensors based on CDs functionalized materials, and recent advances for CDs-based materials (including CDs/carbon nanotubes, CDs/graphene, CDs/conducting polymers and other CDs-based nanomaterials) in electrochemical sensing. Finally, we also discussed some critical challenges and prospects in this field. (C) 2016 Elsevier B.V. All rights reserved.
