Development of Solid-phase Microextraction Fiber Coatings

Abstract

The materials used for the fabrication of solid-phase microextraction fiber coatings are summarized in the current book chapter, including carbon, metal–organic frameworks, covalent organic frameworks, polymers, aerogels, ionic liquids/poly(ionic liquids), and metal oxides. The approaches for loading different coatings on fibers, such as sol–gel, in situ growth, electrodeposition, and gluing methods, are briefly discussed together with the evolution of the supporting substrates. In addition, the limitations of the current fiber coatings and the future development directions of solid-phase microextraction are presented. It is expected to provide important instructions for the selection of appropriate fiber coating materials for target application.
