Abstract
|
This paper presents a comprehensive review concerning the recent trends for the preparation of nanocomposites
(NCs) and their applications in microextraction techniques. NCs are defined as organic–
inorganic hybrid materials in which at least one dimension of one component is less than 100 nm.
Numerous synthesis routes have been introduced to prepare NCs in recent years. This review provides a
general overview regarding the present progress and new applications of NCs toward their synthesis and
use in microextraction techniques, including solid-phase microextraction, stir bar sorptive extraction, and
needle trap extraction, among others.
