The newly developed material is successfully applied for extraction and detection of sulfamethoxazole (SMX) in environmental aqueous samples via a high‐performance liquid chromatography‐diode array detector (HPLC‐DAD). Characterization is accomplished by Fourier transform infrared (FTIR) and field emission scanning electron microscopy/energy dispersive X‐ray (FESEM/EDX), confirming the presence of [BMIM]Cl‐AgNPs on ESM. The optimization of [BMIM]Cl‐AgNPs/ESM‐based SPE method is studied by the one variable at a time (OVAT) approach. Method validation shows good linearity (R2 = 0.9995) in the range of 10–500 µg L−1, with the detection and quantification limits determined to be 3.07 and 9.31 µg L−1 respectively. Additionally, a reusability study shows the developed material can extract SMX up for three cycles without significant reduction in its efficiency. Excellent recoveries (90.07–104.08%) in spiked tap and lake water demonstrate the potential of [BMIM]Cl‐AgNPs/ESM for trace‐level detection of pollutants.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"13 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained particles are characterized with regard to their size, morphology, crystallinity, and magnetic characteristics, using techniques like transmission electron microscopy (TEM), X‐ray diffraction (XRD), and superconducting quantum interference device (SQUID) magnetometry measurements.

NO and NO2 gases, which are hazardous to both human health and the environment, are included in NOx. The rare earth element Ce doped metal oxide semiconductor (MOS) ZnO is employed to reveal their NO gas sensing properties. Based on density functional theory (DFT) calculations, the optimized surface of ZnO (0001), Ce‐doped ZnO (0001), adsorbate structure of NO, and adsorbate NO on the modified ZnO (0001) surface are obtained. The gas sensing properties are examined through adsorption energy, Bader charge analysis, charge density difference (CDD), charge transfer, band structure, total density of state (DOS), and partial density of states (PDOS). For the Ce‐doped ZnO (0001) surface the NO adsorption energy is more negative than the bare ZnO. From the observation of Bader charge analysis, the charge transfer value increases from the substrate to adsorbate after doping with Ce, which indicates that the Ce‐doped ZnO (0001) surface is more favorable for NO gas sensing. Favorable electronic properties and suitable adsorption energy of Ce‐doped ZnO can be a potential gas sensor for NO molecule.

Disease control, epidemiology, and surveillance rely on a One Health approach, as accurate detection can be applied to humans, animals, and the environment. This study represents the first attempt to develop a method for detecting the pathogenic Leptospira santarosai serovar Shermani based on the latex agglutination reaction. The serological activity of the antibody is examined to achieve a high titer of antibody before adsorption onto polystyrene particles. Using a pH medium of 6.8–7.8, total antibody adsorption of up to 3 mg m−2 is achieved. Particle agglutination is observed after incubating the antibody‐adsorbed PS with leptospiral culture for 4 min, revealing a detection limit of 1.7 × 102 leptospires mL−1. Interestingly, the detection limit increased by 1000 times when observing agglutination using spectrophotometer. The test exhibits high specificity with Shermani and shows negligible cross‐agglutination with non‐pathogenic Leptospira and water‐borne bacteria. Agglutination testing in collected water samples from natural sources demonstrates a good correlation with culture technique. This simple and rapid leptospires agglutination detection method can be applied as a screening test in environmental, human, and animal specimens.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"371 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mucosal lesions prompted by the ulceration lead to the penetration through mucosal layers, ultimately resulting in cavity formation and inflammation. Conventional therapeutic modalities for peptic ulcers have shown unfavorable effects, relapses, and numerous drug interactions. The genesis of gastric ulcers is catalyzed via an imbalanced interplay between environmental lesions, defensive mechanisms, and the restoration of gastric mucosa. Lipid based nanotechnology involved in self‐nanoemulsifying drug delivery system (SNEDDS) is being tremendously involved in opening avenues in innovative pharmaceutical delivery systems in terms of improving solubility and regenerative healing against peptic ulcers. Biological macromolecules can be incorporated into SNEDDS to embellish the drug delivery system on an advanced level.

In recent years, the world has experienced the worst epidemic of the current millennium, caused by the Coronavirus 2019, a severe acute respiratory syndrome. This infection can cause severe complications in various organs, such as the stomach, heart, liver, kidney, and brain. Antimicrobial drugs or vaccines can be a practical approach to combating these pathogens. However, there are drug‐resistant or emerging infections that do not have effective drugs or vaccines. Therefore, it is necessary to explore new approaches for early diagnosis, prevention, and effective therapies. So, nanomaterials are widely considered due to their unique properties. This review employs a practical approach to elucidate the role of nanostructures against COVID‐19. Also, the effects and benefits of various types of nanostructures are discussed that have been used to diagnose, prevent, and treat COVID‐19 in recent years. Furthermore, by evaluating different nanostructures, the utilization of biocompatible nanoparticles consisting of selenium and chitosan derivatives is suggested as a promising candidate for industrial use in the fight against COVID‐19.

However, the limited endogenous hydrogen peroxide (H2O2) concentration and resistance to reactive oxygen species in cancer cells hinder the further application of CDT. Here, an H2O2 self‐supplied nanosystem FCaO2@ZIF‐67‐2‐DG‐FA (FZDF) is synthesized to achieve efficient CDT improvement by Ca2+ overload and starvation therapy. Under folic acid‐mediated tumor targeting and endocytosis, the ZIF‐67 layer of FZDF is cleaved in the mildly acidic environment, releasing Co2+ and 2‐deoxy‐D‐glucose (2‐DG). The decomposition of exposed FCaO2 generates sufficient H2O2, which further produces abundant •OH via the Fenton‐like reaction of Co2+. Simultaneously, Ca2+ overload‐triggered mitochondrial dysfunction couples with glycolysis inhibition via 2‐DG‐induced starvation, which disrupts intracellular adenosine triphosphate (ATP) synthesis and amplifies the efficacy of CDT. Silicon nanoparticles released from FCaO2 are applied as in vitro fluorescent probes to image tumor cells overexpressing folate receptors. The results have presented that FZDF can actively accumulate in tumor cells, causing the mitochondrial membrane potential abnormality and a decrease in intracellular ATP content, thereby enhancing the self‐supplied CDT with less effect on normal cells and tissues. This work provides a novel strategy for constructing effective CDT nanosystems by hindering intracellular energy supply.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"1 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141784228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
