[Recent advances in the application of thin-film microextraction]

Thin-film microextraction (TFME), which is a new technique in solid-phase microextraction and correlational research, have gradually attracted the attention of scientists in the field of sample preparation. Because of the high surface area-to-volume ratio and the concurrent increase inthe extraction-phase volume, TFME shows enhanced sensitivity without sacrificing the sampling time, as opposed to other microextraction approaches. Recently, TFME in combination with sample analysis techniques has been widely used for the analysis of forbidden drugs, explosives, pesticides, and veterinary drugs in the pharmaceutical, foodstuff, and environmental industries. This review summarizes the fundamentals, formats, and applications of TFME, as well as its long-term prospects and potential applications.
