An Amperometric Hydrogen Peroxide Sensor Based on Supramolecular Inclusion Complex of β-CD Polymer as Immobilization Matrix

Abstract

Abstract: AnoveLImmobilization approach in the fabrication of hydrogen peroxide is de-scribed. Methylene blue and enzyme were co-immobilized on the electrode by supramolecular function between β-CD polymer(β-CDP) and cation dyes, as well as condensation polymerization between β CDPand glutaric dialdehye. The fabricated H₂O₂sensor exhibited excellent stability and efficient shuttled electron between immobilized horseradish peroxidase(HRP) and the electrode, and responded to H₂O₂in the linear range from 10.μmol/L to 1.1 mmol/L with detection limit of 0.5μmol/L.

Key words: β-CD polymer, Methylene blue, Supramolecular interaction, Immobilization, Biosensor of H₂O₂
