“…[20][21][22] Dispersive solid phase microextraction (dSPME) stands out as an intriguing technique for sample pretreatment, seamlessly integrating the processes of extraction, pre-concentration, sampling, and separation. 23 It has garnered considerable attention due to its capacity to effectively clean up and pre-concentrate targets before instrumental analysis. 24 dSPME has attracted considerable attention in the realm of analysis owing to its notable separation capabilities, ease of operation, and seamless integration.…”

“…Over the last decade, research activities have been oriented toward simplifying, miniaturizing, and minimizing organic solvents used in sample preparation. Two miniaturized techniques, solid-phase microextraction (SPME) and liquid-phase microextraction (LPME), have been developed for this purpose [26]. SPME is a solventless and straightforward method, but it has some drawbacks, such as high cost, sample carry-over, fiber fragility, and limited fiber lifetime [27].…”

Monitoring medications in biological fluids is an essential aspect of patient care, particularly in cases of altered mental status where accurate diagnosis, effective treatment, and even forensic examinations are crucial. In this study, a new approach combining hydrophobic-deep-eutectic and solvent-bar-microextraction (HDE-SBME) followed by a high-performance liquid chromatography-diode array detector (HPLC-DAD) was developed for the simultaneous determination of desipramine, clomipramine, as antidepressant and carbamazepine as antiepileptic agents in untreated human urine and plasma samples. The HDE solvents, synthesized using various ratios of menthol and fatty acids, were utilized in the SBME setups. Computational methods were employed to predict the structure and modes of interaction between HDE and the chosen analytes. Central composite design methodology (CCD) was used for multivariate optimization of the effects of different parameters influencing the extraction efficiency of the proposed method. Under optimized experimental conditions, the calibration graph of the spiked selected drugs in urine and plasma samples demonstrated excellent linearity (R2 ≥ 0.994), with limits of detection/quantification below 0.60/2.02 μg L−1. The extraction recoveries achieved were 88–97%, and the repeatability/reproducibility (RSD%, n = 5) was less than 6.12/7.57. The proposed method was successfully applied to determine selected drugs in patients' urine and plasma samples. The proposed method detects three drugs in patients' urine and plasma samples without using toxic volatile organic solvents. The proposed microextraction technique exhibited a confident sensitivity, feasible operation, and simplicity compared with other published methods. Thus, it can be considered a promising method for monitoring the therapeutic levels of specific antidepressant and antiepileptic drugs in urine and plasma samples.

“…Today, there is a special emphasis is on the "green chemistry" principles [1] as a step forward in polymer synthesis and functionalization. In recent decades, "green chemistry" has focused on finding the "ideal green solvent", where the use of supercritical fluids, such as carbon dioxide [2,3], could at least partially address the environmental impact of large-scale organic solvent use and the generated chemical waste. However, due to several reasons, the alternative where solvents are eliminated entirely proved to be unattainable [4].…”

Molecularly imprinted polymers (MIPs) are established artificial molecular recognition platforms with tailored selectivity towards a target molecule, whose synthesis and functionality are highly influenced by the nature of the solvent employed in their synthesis. Steps towards the “greenification” of molecular imprinting technology (MIT) has already been initiated by the elaboration of green MIT principles; developing MIPs in a solvent-free environment may not only offer an eco-friendly alternative, but could also significantly influence the affinity and expected selectivity of the resulting binding sites. In the current study the first solvent-free mechanochemical synthesis of MIPs via liquid-assisted grinding (LAG) is reported. The successful synthesis of the imprinted polymer was functionally demonstrated by measuring its template rebinding capacity and the selectivity of the molecular recognition process in comparison with the ones obtained by the conventional, non-covalent molecular imprinting process in liquid media. The results demonstrated similar binding capacities towards the template molecule and superior chemoselectivity compared to the solution-based MIP synthesis method. The adoption of green chemistry principles with all their inherent advantages in the synthesis of MIPs may not only be able to alleviate the potential environmental and health concerns associated with their analytical (e.g., selective adsorbents) and biomedical (e.g., drug carriers or reservoirs) applications, but might also offer a conceptual change in molecular imprinting technology.
