“…e DESs, including betaine-ethylene glycol [27], choline chloride-ethylene glycol [28,31], choline chloride-caffeic acidethylene glycol [29], and choline chloride-glycerol [30], have been used as porogen to prepare MIPs. Still, it is necessary to further study DESs-MIPs.…”

“…e DESs can be obtained simply by complexion of quaternary ammonium salts with hydrogen bond donors, which are able to form eutectic mixture. As a result, DESs as porogen have been successfully applied in the synthesis of MIPs, and DESs-MIPs have been used as SPE sorbents [27][28][29][30][31]. However, the application of DESs-MIPs combined with MEPS (DESs-MIPs-MEPS) for extracting levofloxacin from biological samples has not been reported.…”

Fluoroquinolones are considered as gold standard for the prevention of bacterial infections. To improve assessment of antibacterial efficacy, a novel method for determination of levofloxacin was developed and validated. Deep eutectic solvents (DESs) as only green solvent were used as a porogen for preparation of water-compatible molecularly imprinted polymers (MIPs) with a pseudotemplate. The DESs-MIPs were characterized in detail, including scanning electron microscope, nitrogen sorption porosimetry, and Fourier transform-infrared spectra. Clearly, the maximum binding capacity of levofloxacin on DESs-MIPs in water and methanol was 0.216 and 0.077 μmol g−1, respectively. The DESs-MIPs as adsorbing materials were applied in microextraction by packed sorbent (MEPS), and the DESs-MIPs-MEPS conditions were optimized. The DESs-MIPs-MEPS coupled with ultra-high-performance liquid chromatography (UHPLC) was used to determine levofloxacin in human plasma. The method was found linear over 0.05–10 μg mL−1 with coefficient of correlation equal to 0.9988. The limit of detection and limit of quantification were 0.012 and 0.04 μg mL−1, respectively. At three spiked levels, the precision of proposed method was between 95.3% and 99.7% with intraday and interday relative standard deviations ≤8.9%. Finally, the developed method was used to examine levofloxacin from human plasma of 20 hospitalized patients after transrectal ultrasound-guided prostate biopsy, and the average concentration (±SD) of levofloxacin was 2.35 ± 0.99 μg mL−1 in plasma.

“…DLLME-SFO is becoming a popular sample preparation technique, and the type of extraction solvents has been developed in recent years, e.g. [15] and has gradually been considered a new type of green ionic liquid [16][17][18][19]. DESs are composed of two or three components with a melting point lower than its individual components, consisting of hydrogen bond donor (HBD), and hydrogen bond acceptor (HBA) molecules in a certain molar ratio [20].…”

We present a novel dispersive liquid-liquid microextraction method based on the solidification of deep eutectic solvent coupled with high-performance liquid chromatography with a variable-wavelength detection for the detection of five benzoylureas in real water samples. In this work, a green solvent consisting of 1-octyl-3-methylimidazolium chloride and 1-dodecanol was used as an extraction solvent, yielding the advantages of material stability, low density, and a suitable freezing point near room temperature. Parameters that significantly affect extraction efficiency were optimized by the one-factor-at-a-time approach. Under optimal conditions, the recoveries of five target compounds were obtained ranging from 87.39 to 98.05% with correlation coefficients ranging from 0.9994 to 0.9997 for pure water. The limits of detection were in the range of 0.09-0.16 μg/L. The enrichment factors were in the range of 171-188. Linearities were achieved in the range of 0.5-500 μg/L. The proposed method was successfully applied to determine benzoylureas in environmental water samples with a satisfactory recovery of approximately 81.38-97.67%.

“…Ternary deep eutectic solvent (TDES) are formed from one hydrogen bond acceptor (methyltriphenylphosphonium bromide) and two types of hydrogen bond donors (chalcone and formic acid). As a green and designer solvent, DESs have been applied successfully to the modification of materials in catalysis, electricity, extraction, and separation . On the other hand, the synthesis and application of new types of TDESs in MIPs as functional monomers or the modification of MIPs are still in the initial stages.…”

Methyltriphenylphosphonium bromide/chalcone/formic acid, a green ternary deep eutectic solvent, was applied as a functional monomer and dummy template simultaneously in the synthesis of a new molecularly imprinted polymer. Ternary deep eutectic solvent based molecularly imprinted polymers are used as a solid-phase extraction sorbent in the separation and purification of rutin and quercetin from Herba Artemisiae Scopariae combined with high-performance liquid chromatography. Fourier transform infrared spectroscopy and field-emission scanning electron microscopy were applied to characterize the deep eutectic solvent based molecularly imprinted polymers synthesized using different molar ratios of chalcone. The static and competitive adsorption tests were performed to examine the recognition ability of the molecularly imprinted polymers to rutin and quercetin. The ternary deep eutectic solvent consisting of formic acid/chalcone/methyltriphenylphosphonium bromide (1:0.05:0.5) had the best molecular recognition effect. After optimization of the washing solvents (methanol/water, 1:9) and eluting solvents (acetonitrile/acetic acid, 9:1), a reliable analytical method was developed for strong recognition towards rutin and quercetin in Herba Artemisiae Scopariae with satisfactory extraction recoveries (rutin: 92.48%, quercetin: 94.23%). Overall, the chalcone ternary deep eutectic solvent-based molecularly imprinted polymer coupled with solid-phase extraction is an effective method for the selective purification of multiple bioactive compounds in complex samples.
