Non-enzymatic electrochemical detection of cholesterol using β-cyclodextrin functionalized graphene
Highlights
Non-enzymatic route of cholesterol sensing, using MB as redox indicator.
Better solubility of Grp-β-CD-MB (sensing probe) due to hydrophilic interactions.
Entrapment of cholesterol inside Grp-β-CD-MB cavity, forming an inclusion complex.
Cholesterol detection using DPV in a wide range of 1–100 µM and high sensitivity.
