Preparation TiO(2) core-shell nanospheres and application as efficiency drug detection sensor

In this paper, we report the facile preparation of monodisperse titanium dioxide-diltiazem/tetrachlorobismuth core-shell nanospheres (TiO(2)@DTMBi), in which, diltiazem (DTM)/tetrachlorobismuth (BiCl(4)) complexes were employed as electroactive materials. The morphology, size, formation, and structu...

Descripción
Sumario:In this paper, we report the facile preparation of monodisperse titanium dioxide-diltiazem/tetrachlorobismuth core-shell nanospheres (TiO(2)@DTMBi), in which, diltiazem (DTM)/tetrachlorobismuth (BiCl(4)) complexes were employed as electroactive materials. The morphology, size, formation, and structure of the obtained TiO(2)@DTMBi spheres were investigated by transmission electron microscopy, scanning electron microscopy, dynamic light scattering, Fourier transform infrared spectroscopy, and X-ray diffraction. The optimal condition of obtained monodisperse 40-nm TiO(2)@DTMBi spheres was researched. The results of using TiO(2)@DTMBi nanospheres as proposed drug sensor indicate a wide linear range (10(-7) to 10(-1) M) and a very low detection limit of 0.20 μg/mL.
