Fabrication and Its Glucose Detection Application of a Nonenzymatic Pt-Pd/UCNTs Biosensor

Abstract:

Fabrication and its electrocatalytic property on glucose of platinum-palladium/unzipped carbon nanotubes(Pt-Pd/UCNTs) nonenzymatic biosensor were studied in this manuscript.Scanning electron mi-croscopy(SEM),X-ray photoelectron spectroscopy(XPS),and cyclic voltammogram(CV) results indicated Pt-Pd nanoparticles were well-dispersed on the surface of UCNTs/GCE;compared with UCNTs,Pd/UCNTs,and Pt/UCNTs modified electrodes,Pt-Pd/UCNTs modified electrode exhibited strong electro-catalytic activity toward glucose oxidation,such as faster catalytic respond and larger respond current,and had better selectivity.
