Advances in magnetic nanomaterials for sample pretreatment and future prospects

Adsorbent materials play a key role in sample preparation techniques. With the recent developments in this field, increasing numbers of nanomaterials are being used as adsorbents to improve the extraction efficiency of the target compound. Because of their advantages such as ease of separation, facile surface modification, strong adsorption capacity, and good biocompatibility, magnetic nanomaterials have been widely used for sample preparation techniques in analytical chemistry. In this paper, research trends in magnetic nanomaterials and their application to magnetic solid-phase extraction and other sample pretreatment techniques are summarized and discussed. The stability, force, specific surface area, and pore size control of the magnetic nanomaterials are also described. The application prospects of magnetic nanomaterials in separation science are prospected, which provides a clear outlook and reference for further research into their application.
