Spherical cellulose/chitosan aerogel–supported MOF-199 for the magnetic solid-phase extraction of benzodiazepines from urine

Article

作者: Fu, Defeng ; Lü, Ting ; Zhang, Suling ; Liu, Hengli ; Zhao, Hongting ; Zhang, Dong

Metal-organic frameworks (MOFs) are promising materials for sample pretreatment. The performance improvement of powdered MOFs is hindered by their aggregation and difficult recovery. To overcome these issues, a biodegradable lightweight spherical aerogel was used as a support for the in situ growth of copper-based MOFs (MOF-199). Furthermore, Fe₃O₄ nanoparticles were incorporated into the aerogel to achieve magnetic properties. Thus, hybrid aerogel spheres containing MOF-199 supported on magnetic oxidized cellulose nanofiber/carboxymethyl chitosan (MOF-199@mag-CNF/CMC) were fabricated. The effects of Fe₃O₄ loading amount and organic-ligand concentration on the properties (spherical geometry and mechanical strength) of the hybrid aerogel spheres were studied. Their potential application in the extraction of benzodiazepines (BZPs) from urine samples prior to liquid chromatography-mass spectrometry was evaluated. The highly dispersed MOF-199 crystals on the spherical aerogel effectively overcame the inherent structural shrinkage of the bare aerogel spheres; thus, the MOF-199@mag-CNF/CMC aerogel spheres were robust and could withstand repeated use for at least eight consecutive extraction cycles. Further, MOF-199@mag-CNF/CMC exhibited improved BZP extraction efficiency, which was 2.5-11.6 times higher than that of bare Cu²⁺@mag-CNF/CMC aerogel spheres, primarily due to additional π-π interaction and H-bonding as well as improved specific surface area. Parameters influencing the extraction and desorption processes were also comprehensively investigated. Under optimal conditions, this method provided a wide linear range of 0.1-10 µg/L (R² > 0.995) and good precision (2.8-6.7% for intra-day; 1.9-7.8 % for inter-day). The limits of detection and quantification ranged from 0.02 to 0.11 µg/L and from 0.06 to 0.33 µg/L, respectively. The recoveries for the urine samples spiked with three concentrations of BZPs ranged from 73.9 % to 114.1 %. The proposed method is simple, sensitive and eco-friendly and can be used for the determination of BZPs from urine for clinical and forensic examinations.

Estrogenic disruption effects and formation mechanisms of transformation products during photolysis of preservative parabens

Article

The ubiquitous presence of emerging contaminants (ECs) in the environment and their associated adverse effects has raised concerns about their potential risks. The increased toxicity observed during the environmental transformation of ECs is often linked to the formation of their transformation products (TPs). However, comprehension of their formation mechanisms and contribution to the increased toxicity remains an unresolved challenge. To address this gap, by combining quantum chemical and molecular simulations with photochemical experiments in water, this study investigated the formation of TPs and their molecular interactions related to estrogenic effect using the photochemical degradation of benzylparaben (BZP) preservative as a representative example. A non-targeted analysis was carried out and three previously unknown TPs were identified during the transformation of BZP. Noteworthy, two of these novel TPs, namely oligomers BZP-o-phenol and BZP-m-phenol, exhibited higher estrogenic activities compared to the parent BZP. Their IC₅₀ values of 0.26 and 0.50 μM, respectively, were found to be lower than that of the parent BZP (6.42 μM). The binding free energies (ΔG_bind) of BZP-o-phenol and BZP-m-phenol (-29.71 to -23.28 kcal·mol^-1) were lower than that of the parent BZP (-20.86 kcal·mol^-1), confirming their stronger binding affinities toward the estrogen receptor (ER) α-ligand binding domain. Subsequent analysis unveiled that these hydrophobic residues contributed most favorably to ER binding, with van der Waals interactions playing a significant role. In-depth examination of the formation mechanisms indicated that these toxic TPs primarily originated from the successive cleavage of ester bonds (OCH₂C₆H₅ and COO group), followed by their combination with BZP*. This study provides valuable insight into the mechanisms underlying the formation of toxic TPs and their binding interactions causing the endocrine-disrupting effects. It offers a crucial framework for elucidating the toxicological patterns of ECs with similar structures.

Numerical optimization of auxiliary biaxial receiver to detect blind zone of pulsed coherent wind lidar

Article

作者: Zhao, Mingguang ; Wang, Huaijin ; Yu, Zhibin ; Li, Mengpei

The conventional pulsed monostatic coaxial coherent Doppler wind lidar (CDWL) has a blind detection zone of tens of meters, causing the loss of near-field wind field data. While maintaining the long-range detection capabilities of pulsed lidar, we introduce a novel auxiliary biaxial receiver (ABR) aimed at acquiring dependable coherent signals within blind zones. This is achieved by incorporating a receiver in close proximity to the monostatic coaxial transceiver (MCT), thereby mitigating end-face reflections and laser pulse tailing effects. A specific model of multiple aperture coherent wind detection is established for the ABR system without blind zone problem (BZP). The numerical simulations demonstrate that the biaxial receiver with reasonable design can meet the detection needs of the entire range of the blind zone. By using an ABR with a smaller focal length under appropriate transceiver pointing and general pointing accuracy, the BZP can be solved. The study also exhaustively obtained all parameter combinations that can solve the near-field BZP for a specific system. The results provide a new idea and engineering design guidance for the optical system design of pulsed CDWL without BZP.
