ELECTROSPINNING APPLIED TO THE DEVELOPMENT OF ADSORBENT NANOFIBERS AIMING AT IMPROVING SOLID PHASE (MICRO)EXTRACTION TECHNIQUES. The limitations and challenges associated with the complex analyte-matrixinterfering interactions make the development of new sorbent materials an attractive line in several research areas, ranging from the synthesis and characterization to the application of these materials. Among the different strategies for manufacturing sorbent nanomaterials, the electrospinning of nanofibers based on polymeric solutions incorporated into Metal-Organic Frameworks (MOFs), Molecularly Imprinted Polymers (MIPs) and Nanoparticles (NPs) have represented in recent years, one of the methods more versatile and promising with regard to obtaining materials with large surface area and potential for functionalization and chemical modification. In this sense, the objective of this contribution is to highlight recent work aimed at the synthesis of electrospun nanofibers applied in adsorption and sample preparation processes, highlighting the synthetic nanofiber strategies based on MOFs, MIPs and NPs and the main challenges and perspectives of the applications, although little explored, of these materials in solid phase extraction and microextraction techniques.
