Abstract
The purpose of this study is to develop a rapid and efficient purification method for determination of veterinary drug based on magnetic silica nanospheres. We have described a scheme for preparing C18/C8-functionalized magnetic silica nanospheres (Fe3O4@Si-C8/C18) for potential use as capture probes in sample pretreatment. The magnetic Fe3O4 particles were firstly coated by tetraethyl orthosilicate to form magnetic silica nanospheres, which were then modified by both trimethoxy(octadecyl)silane (C18) and trimethoxy(octyl)silane (C8). The Fe3O4@Si-C8/C18 thus prepared could exhibit strong superparamagnetism, highly efficient capture ability, easy-to-use for isolation, and enrichment of veterinary drug residues in food.
