摘要:
A novel immobilization approach in the fabrication of hydrogen peroxide is described. Methylene blue and enzyme were co-immobilized on the electrode by supramolecular function between beta-CD polymer(beta-CDP) and cation dyes, as well as condensation polymerization between beta-CDP and glutaric dialdehye, The fabricated H2O2 sensor exhibited excellent stability and efficient shuttled electron between immobilized horseradish peroxidase (HRP) and the electrode, and responded to H2O2 in the linear range from 1.0 mu mol/L to 1.1 mmoI/L with detection limit of 0.5 mu mol/L.
