Abstract
In general, the analysis of biological matrices is challenging and a sample preparation step employing extraction/cleanup techniques is required. Liquid-phase microextraction using deep eutectic solvents has been exploited in numerous applications because these solvents exhibit fascinating physico-chemical properties in addition to simple and straightforward preparation. Varied configurations and strategies have been examined for the determination of different classes of analytes, and these methodologies offer environmentally friendly workflows with low solvent and sample consumption, rapid and simple experimental procedures, and satisfactory analytical performance. In this review, developments related to the use of deep eutectic solvents in microextraction approaches for the analysis of biological matrices are briefly discussed with a focus on studies reported from 2017 to 2021.
