Paper-based sorptive phases are promising tools in sample preparation because of their high surface-to-volume ratio, porosity, and versatility. This article discusses the synthesis of paper-based sorptive phases by dip coating. This procedure has allowed a wide variety of phases coated with polymers, nanoparticles, and their combination to be synthesized. This article presents the synthesis, types of coatings, and extraction devices, to highlight the versatility and potential of these materials to the analytical community, particularly for sample preparation.
