[PMID: 38917927 DOI: 10.1016/j.ijbiomac.2024.133384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 06/02/2024] [Accepted: 06/21/2024] [Indexed: 06/27/2024]
Abstract
This study introduces a novel approach for the separation of indacrinone (IC) enantiomers, crucial in treating edema, hypertension, and hyperuricemia. A cationic biopolymer from furan-2-ylmethylhydrazine-cellulose (FUH-CE), derived from cyanoethyl cellulose (CEC), serving as a substrate in molecular imprinting. A key innovation is the use of the Diels-Alder reaction for efficient cross-linking with bis(maleimido)ethane (BME). This chemical strategy resulted in molecularly imprinted microparticles with high selectivity for the S-IC enantiomer, which can be eluted by adjusting the solution's pH. Extensive characterization confirmed the chemical modifications and selective binding efficacy of these biopolymers. Utilizing separation columns, our method achieved an impressive chiral resolution of (±)-IC, with an enantiomeric excess (ee) of 95 % for R-IC during the loading phase and 97 % for S-IC during elution. Under optimized conditions, the biopolymer demonstrated a maximum binding capacity of 131 mg/g at pH 6. This advanced approach represents a significant advancement in chiral separation technology, offering a robust and efficient technique for the selective isolation of enantiomers. This method not only enhances potential targeted therapeutic applications but also provides a scalable solution for industrial chiral separations.

Abstract
Rapid separation and enrichment of targets in biological matrixes are of significant interest in multiple life sciences disciplines. Molecularly imprinted polymers (MIPs) have vital applications in extraction and sample cleanup owing to their excellent specificity and selectivity. However, the low mass transfer rate, caused by the heterogeneity of imprinted cavities in polymer networks and strong driving forces, significantly limits its application in high-throughput analysis. Herein, one novel metal affinity-oriented surface imprinting method was proposed to fabricate an MIP with an ultrathin imprinting layer. MIPs were prepared by immobilized template molecules on magnetic nanoparticles (NPs) with metal ions as bridges via coordination, and then polymerization was done. Under the optimized conditions, the thickness of the imprinting layer was merely 1 nm, and the adsorption toward VAL well matched the Langmuir model. Moreover, it took just 5 min to achieve adsorption equilibrium significantly faster than other reported MIPs toward VAL. Adsorption capacity still can reach 25.3 mg/g ascribed to the high imprinting efficiency of the method (the imprinting factor was as high as 5). All evidence proved that recognition sites were all external cavities and were evenly distributed on the surface of the NPs. The obtained MIP NPs exhibited excellent selectivity and specificity toward VAL, with good dispersibility and stability. Coupled with high-performance liquid chromatography, it was successfully used as a dispersed solid phase extraction material to determine VAL in serum. Average recoveries are over 90.0% with relative standard deviations less than 2.14% at three spiked levels (n = 3). All evidence testified that the MIPs fabricated with the proposed method showed a fast trans mass rate and a large rebinding capacity. The method can potentially use high-throughput separation and enrichment of target molecules in batch samples to meet practical applications.

Synthesis of molecularly imprinted polymer as a nanosorbent for dispersive magnetic micro solid-phase extraction and determination of valsartan in biological samples by UV-Vis Spectrophotometry: Isotherm, kinetics, and thermodynamic studies. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 296:122656.

Abstract
A magnetic molecularly imprinted polymer (MIP) was synthesized by precipitation polymerization utilizing Fe3O4@SiO2-MPS as a magnetic core, itaconic acid as a functional monomer, azobisisobutyronitrile as an initiator, and ethylene glycol dimethacrylate as a cross linker. It was then applied as a nanosorbent for dispersive magnetic micro solid phase extraction (DM-µ-SPE) and determination of valsartan in biological fluids. The morphology and structure of magnetic MIP were characterized by Fourier-transform infrared spectroscopy, Field Emission Scanning electron microscopy, Vibrating sample magnetometer, Energy dispersive x-ray analysis, and Thermogravimetric analysis. The influence of operation conditions on sorption, such as pH (4-10), contact time (10-25 min), initial concentration (1-30 mg L-1), and temperature (25-40 °C) was investigated. After the extraction step, the valsartan concentration was determined by UV-Vis spectrophotometer at 253 nm. The isotherm and kinetic of valsartan sorption were best fitted by the Langmuir model (R2 = 0.987) and the Pseudo second-order kinetic model (R2 = 0.971), respectively. The maximum monolayer sorption capacity for magnetic MIP was obtained to be 4.56 mg g-1. The analytical approach demonstrated favorable figures of merit, with a linear dynamic range of 10-100 µg L-1, a low detection limit of 0.56 µg L-1, and an acceptable preconcentration factor of 5 acquired in optimum conditions. The recoveries of the suggested technique at three spiked levels of analysis were in the range of 101 %-102 %. Valsartan was extracted from various real samples (urine and human blood plasma samples) utilizing the proposed magnetic nanosorbent, and the results exhibited that magnetic MIP was favorable for extraction and measurement of trace amounts of valsartan in biological samples.

Abstract
Molecular imprinting technology has been around for almost a century, and we have witnessed dramatic advancements in the overall design and production of molecularly imprinted polymers (MIPs), particularly in terms of possible formats of the final products when it comes to truly resembling antibody substitutes, i.e., MIP nanoparticles (MIP NPs). Nonetheless, the overall technology appears to struggle to keep up with the current global sustainability efforts, as recently elucidated in the latest comprehensive reviews, which introduced the "GREENIFICATION" concept. In this review, we will try to elucidate if these advancements in MIP nanotechnology have indeed resulted in a sustainability amelioration. We will do so by discussing the general production and purification strategies for MIP NPs, specifically from a sustainability and biodegradation perspective, also considering the final intended application and ultimate waste management.

Enrichment of psychotropic drugs using rhamnolipid bioaggregates after electromembrane extraction based on an agarose gel using a rotating electrode as a green and organic solvent-free strategy. J Chromatogr A 2021; 1655:462500.

Abstract
We here present an efficient approach for the tandem extraction of psychotropic drugs using biodegradable materials. In this regard, gel electromembrane extraction (G-EME) was combined with the emulsification-based microextraction (ME) technique by rhamnolipid bioaggregates as a green extraction approach. The tandem extraction technique consists of two stages: (i) extraction of psychotropic drugs from human urine samples to the acceptor phase situated on the other side of the agarose gel membrane, and (ii) transfer of analytes from the acceptor phase into a colloidal phase of rhamnolipid biosurfactants. The colloidal phase was formed by adding rhamnolipid biosurfactants to the extracted phase of the first step. The colloidal phase was finally injected into a liquid chromatographic system for quantitative analysis. G-EME mechanism is based on electrokinetic migration of charged species toward oppositely charged electrode located in the acceptor solution under the influence of the electric field. After extraction, the analytes were trapped in an emulsion phase floating on the surface of the solution and at the end were injected into the liquid chromatographic system. The method provided good linearity in the ranges of 5-100 and 10-100 μg. L-1 for methamphetamine and amphetamine, respectively with (r2 > 0.992). Also, the detection limits (LODs) were 1 and 5 μg. L-1 for methamphetamine and amphetamine, respectively. The mean extraction recoveries by G-EME-ME for real samples at three spiked concentrations were in the range 95.9-101.1% and complete analytical workflow within only 18 min.

Abstract
The importance of magnetic nanomaterials and magnetic hybrid materials, which are classified as new generation materials, in analytical applications is increasingly understood, and research on the adaptation of these materials to analytical methods has gained momentum. Development of sample preparation techniques and sensor systems using magnetic nanomaterials for the analysis of inorganic, organic and biomolecules in biological samples, which are among the samples that analytical chemists work on most, are among the priority issues. Therefore in this review, we focused on the use of magnetic nanomaterials for the bioanalytical applications including inorganic and organic species and biomolecules in different biological samples such as primarily blood, serum, plasma, tissue extracts, urine and milk. We summarized recent progresses, prevailing techniques, applied formats, and future trends in sample preparation-analysis methods and sensors based on magnetic nanomaterials (Mag-NMs). First, we provided a brief introduction of magnetic nanomaterials, especially their magnetic properties that can be utilized for bioanalytical applications. Second, we discussed the synthesis of these Mag-NMs. Third, we reviewed recent advances in bioanalytical applications of the Mag-NMs in different formats. Finally, recently literature studies on the relevance of Mag-NMs for bioanalysis applications were presented.
