Abstract
The clinical utility of gemcitabine, an antimetabolite antineoplastic agent applied in various chemotherapy treatments, is limited due to the required intravenous injection. Although chemical structure modifications of gemcitabine result in enhanced oral bioavailability, these modifications compromise complex synthetic routes and cause unexpected side effects. In this study, gemcitabine-loaded glycocholic acid-modified micelles (Gem-PPG) were prepared for enhanced oral chemotherapy. The in vitro transport pathway experiments revealed that intact Gem-PPG were transported across the intestinal epithelial monolayer via an apical sodium-dependent bile acid transporter (ASBT)-mediated pathway. In mice, the pharmacokinetic analyses demonstrated that the oral bioavailability of Gem-PPG approached 81%, compared to less than 20% for unmodified micelles. In addition, the antitumor activity of oral Gem-PPG (30 mg/kg, BIW) was superior to that of free drug injection (60 mg/kg, BIW) in the xenograft model. Moreover, the assessments of hematology, blood chemistry, and histology all indicated the hypotoxicity profile of the drug-loaded micelles.

Abstract
The increase in the production and consumption of pharmaceuticals increases their presence in the global environment, which may result in direct threats to living organisms. For this reason, there is a need for new methods to analyze drugs in environmental samples. Here, a new procedure for separating and determining selected drugs (diclofenac, ibuprofen, and carbamazepine) from bottom sediment and water samples was developed. Drugs were determined by ultra-high performance liquid chromatography coupled with an ultraviolet detector (UHPLC-UV). In this work, a universal and single-step sample treatment, based on supramolecular solvents (SUPRAS), was proposed to isolate selected anticonvulsants and nonsteroidal anti-inflammatory drugs (NSAIDs) from sediment samples. The following parameters were experimentally selected: composition of the supramolecular solvent (composition THF:H2O (v/v), amount of decanoic acid), volume of extractant, sample mass, extraction time, centrifugation time, and centrifugation speed. Finally, the developed procedure was validated. A Speedisk procedure was also developed to extract selected drugs from water samples. The recovery of analytes using the SUPRAS procedure was in the range of 88.8-115%, while the recoveries of the Speedisk solid-phase extraction procedure ranged from 81.0-106%. The effectiveness of the sorption of the tested drugs by sediment was also examined.

Abstract
Supramolecular solvents (SUPRAS) have progressively become a suitable alternative to organic solvents for sample preparation in chromatographic analysis. The inherent properties of these nanostructured solvents (e.g. different polarity microenvironments, multiple binding sites, possibility of tailoring their properties, etc.) offer multiple opportunities for the development of innovative sample treatment platforms not approachable by conventional solvents. In this review, major achievements attained in the combination SUPRAS-chromatography in the last 20 years as well as the challenges that should be addressed in the near future are critically discussed. Among achievements, particular attention is paid to the theoretical and practical knowledge gained that has helped make substantial progress in the area. In this respect, advances in the understanding of the mechanisms involved in SUPRAS formation and SUPRAS-solute interactions driving extractions are discussed, with a view to the setting up of knowledge-based extraction procedures. Likewise, the strategies followed to improve the compatibility of SUPRAS extracts with liquid and gas chromatography and adapt SUPRAS-based extractions to different formats are presented. Ongoing efforts to apply SUPRAS in multicomponent extractions and synthesize tailored SUPRAS for the development of innovative sample treatments are highlighted. Among challenges identified, discussion is focused on the automation of SUPRAS-based sample treatment and the elucidation of SUPRAS nanostructures, which are considered essential for their acceptance in routine labs and the design of tailored SUPRAS with programmed functions.

Abstract
Background and Objective:
A rapid, simple and environmental friendly supramolecular
solvent (SUPRAS) based liquid-liquid microextraction method for preconcentration of ciprofloxacin
(CIPRO), danofloxacin (DANO) and enrofloxacin (ENRO) from wastewater was developed.
Methods:
This microextraction technique was coupled with high-performance liquid chromatography
equipped with a diode array detector (HPLC-PDA) for detection and separation of the antibiotics. The
SUPRAS composed of decanoic acid and tricaprylymethylammonium chloride. Optimum conditions for
the extraction and preconcentration of all the antibiotics were obtained using surface response methodology
(RSM) based on Box-Behnken design.
Results:
Under optimum conditions, the limits of detection (LOD) and limit of quantification (LOQ)
ranged from 0.06-0.14 µg L−1 and 0.22-0.47 μg L−1, respectively with the preconcentration factors ranging
from 153-241. The linear dynamic ranges were between LOQ and 850 µg L−1 with correlation coefficients
ranging from 0.9928 to 0.9999. The intra-day (n = 15) and inter-day (n = 5) precisions (expressed
in terms of %RSD) for 50 µg L−1 of CIPRO, DANO and ENRO were in the range of 3.3–4%
and 4.1–5.8%, respectively.
Conclusion:
Lastly, the developed method was used for the extraction, preconcentration and quantification
of selected CIPRO, DANO and ENRO in influent and effluent wastewater samples.

Abstract
A simple, rapid, sensitive and eco-friendly method has been developed for the simultaneous determination, preconcentration and extraction of phthalate esters (dimethyl phthalate, diethyl phthalate, dibutyl phthalate, benzyl butyl phthalate and bis(2-ethylhexyl) phthalate) in perfumes using dispersive liquid-liquid microextraction (DLLME) coupled to gas chromatography-mass spectrometry (GC-MS). Various factors affecting the DLLME efficiency, including the type and volume of the extracting and dispersing solvents, salt addition and vortex extraction time were optimized. Under optimum conditions, the proposed method provided low detection limits (0.003-0.070 ng mL-1), high extraction recovery (85.6-95.8%), wide linearity range (1.0-1000 ng mL-1) with good regression coefficients (>0.9984) and good precision (RSD% < 4.2%). The optimized method was successfully utilized for the analysis of different branded perfume samples and satisfactory results were obtained.

Abstract
AbstractA simple, fast and environmental friendly vortex assisted-supramolecular solvent based microextraction (VA-SSME) method was developed for the preconcetration of triclosan in wastewater prior to UV spectrophotometric determination. To achieve maximum sensitivity and accuracy for the target analyte, the experimental parameters affecting the VA-SSME procedure were optimized using response surface methodology (RSM). Under optimised conditions, the correlation coefficient (R2) and recoveries were 0.9994 and 100.31-118.5%, respectively. The intra-day (repeatability) and inter-day (reproducibility) precisions expressed in terms of relative standard deviation (RSD) were 2-4% and 5.2%, respectively. The preconcentration factor and limits of detection (LOD) and quantification (LOQ) were found to be 90, 0.28 μg L−1 and 0.92 μg L−1, respectively. The developed VA-SSME/UV method was applied for the determination of triclosan in real samples collected over a period of three months. The analytical results obtained showed that triclosan was frequently detected in influent wastewater samples but was not detected in effluent samples.

Abstract
Phthalic acid esters (PEs) were preconcentrated from cleaning products, detergents and cosmetics using ultrasound assisted extraction (UAE) in the presence of acetonitrile, and then submitted to dispersive liquid-liquid microextraction (DLLME). For DLLME, 3mL of acetonitrile extract, 150μL carbon tetrachloride and 10mL aqueous solution were used. The enriched organic phase was evaporated, reconstituted with 25μL acetonitrile and injected into a liquid chromatograph with a mobile phase (acetonitrile:10mM ammonium acetate, pH 4) under gradient elution. Detection was carried out using both diode-array (DAD) and electrospray-ion trap-tandem mass spectrometry (ESI-IT-MS/MS) in the multiple reaction monitoring mode (MRM) of the positive fragment ions. Quantification was carried out using matrix-matched standards. Detection limits were in the range 0.04-0.45ngmL(-1) for the six PEs considered. The recoveries obtained were in the 84-124% range, with RSDs lower than 10%. Thirty three different cleaning products were analyzed. The most frequently found compound was diethyl phthalate.
