Molecularly imprinted polymers for solid-phase microextraction.

Solid-phase microextraction (SPME) is widely used in analytical laboratories for the analysis of organic compounds, thanks to its simplicity and versatility. However, the current commercially available fibers are based on nonselective sorbents. Molecularly imprinted polymers (MIPs) are stable polymers with selective molecular recognition abilities, provided by the template used during their synthesis. In the present review, the different strategies followed during the last years for the obtainment of MIP fibers to be used in SPME are described. The advantages and drawbacks of each methodology as well as the future expected trends are discussed.
