Preparation of silicate nanotubes and its application for electrochemical sensing of clozapine

Abstract Novel silicate nanotubes (SNTs) was prepared by hydrothermal method. The SNTs was characterized by transmission electron microscopy (TEM), Energy-dispersive X-ray (EDX), X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The SNTs exhibited excellent properties such as uniform dimension, and larger specific surface area, which was attractive for the fabrication of chemical modified electrode. Clozapine was chose as a model to demonstrate the performance of the SNTs electrode. The enhanced electrochemical response of clozapine at SNTs electrode was observed as compared with bare glass carbon electrode. The strategy presented here opens a new way for the development of electrochemical sensors based on SNTs.
