摘要：

A composite of carbon nanotubes with yttrium modified titania particles (Y/TiO2-CNT) is synthesized and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and Fourier transform infrared spectroscopy (FTIR). The electrochemical behavior of amino group (Lysine) is investigated by cyclic voltammetery (CV). The response mechanism of the synthesized biosensor is proposed to be the combination of electrostatic and electrical interactions of CNTs with amino group. Excellent sensitivity, repeatability, stability, selectivity and recovery for the potentiometric determination of Lysine in the range of 5mM to 25mM concentrations are obtained.
