The fabrication of coatings for fiber solid-phase microextraction (SPME) is the main objective in many of the scientific research developed in the area. For this purpose, a variety of NMs have been used such as carbon-based NMs, especially carbon nanotubes (CNTs) and graphene, metallic and silica-based NMs, and more recently, metal-organic frameworks (MOFs). NMs have also been used to prepare new sorbents for other microextraction techniques such as in-tube solid-phase microextraction(ITSPME) and stir bar sorptive extraction (SBSE). The employment of magnetic nanoparticles (MNPs) has recently been introduced in microextraction, which leads to a new technique termed magnetic IT-SPME. Although the number of applications is still low, NMs are also receiving increasing attention in the main techniques of liquid phase microextraction namely, singe drop microextraction (SDME), hollow-fiber liquidphase microextraction (HF-LPME) and dispersive liquid-liquid microextraction (DLLME).
