Multiwalled carbon nanotubes/ZrO2-Pt(MWCNTs/ZrO2-Pt) composite was synthesized by a chemical route. The structure and composition of the MWCNTs/ZrO2-Pt composite were confirmed by means of transmission electron microscopy, and Raman spectroscopy. Due to the good electrochemical activity property of MWCNTs/ZrO2-Pt composite, a glucose biosensor was constructed by absorbing glucose oxidase (GOD) on the hybrid material. A direct electron transfer process is observed at the MWCNTs/ZrO2-Pt/GOD-modified glassy carbon electrode. The glucose biosensor has a linear range from 4.0 to 24.0 mM, which is suitable for glucose determination by real samples. It should be worthwhile noting that, from 4.0 to 12.0mM, the cathodic peak currents of the biosensor decrease linearly with increasing the glucose concentrations in human blood. Meanwhile, the resulting biosensor can also prevent the effects of interfering species. Moreover, the biosensor exhibits satisfying reproducibility, good operational stability and storage stability. Therefore, the MWCNTs/ZrO2-Pt /GOD biocomposite could be promisingly applied to determine blood sugar concentration in the practical clinical analysis.
