3D graphene/hydroxypropyl-β-cyclodextrin nanocomposite as an electrochemical chiral sensor for the recognition of tryptophan enantiomers

A novel and facile chiral sensing platform has been designed for electrochemical enantiomer recognition based on the coupling of three-dimensional-graphene with hydroxypropyl-β-cyclodextrin (3D-G/HP-β-CD).
