Integration of β-cyclodextrin into graphene quantum dot nano-structure and its application towards detection of Vitamin C at physiological pH: A new electrochemical approach

Stable electroactive modified electrode using electrodeposition of GQD in the presence β-CD was prepared by cyclic voltammetry. It was found that the β-CD-GQD-GCE exhibit good catalytic activity for the oxidation of Vitamin C at a reduced overpotential and it has a significant high response for Vitamin C oxidation.165
