Therefore, the detection of CTC is of great significance. In this study, gold nanoclusters (AuNCs) were synthesized under certain conditions with Nuclear Fast Red as a stabilizer, chloroauric acid as the raw material, and sodium borohydride as the reducing agent. The synthesized AuNCs exhibited an optimal excitation wavelength of 376 nm and an optimal emission wavelength of 513 nm. It was observed that CTC could effectively enhance the fluorescence of the synthesized AuNCs at an emission wavelength of 424 nm when excited at 352 nm. The fluorescence intensity of the AuNCs system in the absence (F0) and presence (F) of CTC was measured. A good linear relationship was observed between the fluorescence intensity enhancement value (ΔF = F–F0) and the concentration of CTC in the range of 10.0–90.0 μM. The linear equation was ΔF = 8.67c + 123.5, with a limit of detection of 2.0 μM (3σ/k). Thus, AuNCs could be used as fluorescent probes for the detection of CTC concentration. The applicability of the method was validated using a spiked recovery test with river water samples. The recovery rates ranged from 94.0 to 103.4%, demonstrating the potential of this method for detecting CTC concentrations in river water samples.","PeriodicalId":606,"journal":{"name":"Journal of Analytical Chemistry","volume":"80 7","pages":"1196 - 1202"},"PeriodicalIF":1.1,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of near- and mid-region IR spectra made it possible to identify specific features of the chemical composition and structure of the studied samples and ensured the reliable separation of natural and imitation caviar. The use of Raman spectroscopy contributed to the determination of characteristic spectral differences associated with the protein and lipid composition and the presence of carotenoids, by which the samples could be clearly differentiated. The use of principal component analysis (PCA), hierarchical cluster analysis (HCA), and soft independent modeling of class analogy (SIMCA) algorithms increased the classification accuracy and ensured the separation of samples by the fish species.

Characterizations of the synthesized MIP were investigated by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, thermogravimetric analysis, and Brunauer–Emmett–Teller. Also, the optimization of desorption parameters such as time and temperature was performed by a central composite design-response surface methodology. First, extraction and determination of MEK and n-hexane were conducted by the proposed method on the laboratory scale and then used in a field study for shoe factory workers. Based on the results, the optimal desorption temperature and time were obtained at 190°C over 120 s, respectively. The analytical performance of NTD-MIP was confirmed by a recovery level > 98.7% and precision by relative standard deviations between 2.06 and 8.05%. Furthermore, the limit of detection and the limit of quantitation of the NTD-MIP method were determined in the range of 0.024–0.020 and 0.080–0.069 ppm, respectively. It is worth mentioning that NTD-MIP showed a high analytical performance compared to the standard the National Institute for Occupational Safety and Health (NIOSH) method in all evaluated validation parameters. These results elucidated that the proposed NTD-MIP method can be employed as an eco-friendly, efficient, and selective procedure for monitoring n-hexane and MEK in exhaled air.","PeriodicalId":606,"journal":{"name":"Journal of Analytical Chemistry","volume":"80 7","pages":"1152 - 1162"},"PeriodicalIF":1.1,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ZAB260, a potent antibacterial agent targeting DNA gyrase and topoisomerase IV, offers a promising approach against antibacterial resistance, including fluoroquinolone-resistant strains. The study also emphasizes the importance of establishing an efficient extraction method to overcome the challenges associated with the low solubility of ZAB260, enabling precise quantification in complex cream formulations. Preliminary method development (mobile phase composition, pH of the mobile phase, selection of column) was carried out using S-Matrix Fusion Quality-by-Design software in conjunction with Agilent OpenLab ChemStation software. A C18 column with integrated phenyl functionality and a gradient mobile phase consisting of 10 mM potassium dihydrogen phosphate (pH 2.5) and acetonitrile was used for ultraviolet detection at 256 nm. The method was validated and demonstrated excellent linearity (correlation coefficient > 0.995), precision (RSD < 2%), and recovery (98–102%, RSD < 2%). The lack of a dedicated framework for the simultaneous estimation of parabens and poorly soluble NBTI in cream has prompted the need for a reliable analytical method. This study fills this gap by offering a comprehensive solution for simultaneous determination with accuracy, sensitivity, and robustness.","PeriodicalId":606,"journal":{"name":"Journal of Analytical Chemistry","volume":"80 6","pages":"1052 - 1061"},"PeriodicalIF":1.1,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing PFOA detection methods are often applied with high equipment and operation costs. This study developed a high-performance liquid chromatography-fluorescence detection method with pre-column derivatization for PFOA determination. This method was applied to the detection of PFOA in the effluent from disk-tubular reverse osmosis (DTRO) membrane treatment of leachate at a waste incineration plant. The chromatographic and derivatization conditions of the method were systematically optimized. PFOA concentrations were indirectly measured through the fluorescence peak area of its derivative with 3-bromoacetyl coumarin. The optimized method operates under the following conditions: a C18 column, a mobile phase consisting of acetonitrile and water (60 : 40, v/v) at 30°C, and fluorescence detection at an excitation wavelength of 305 nm and an emission wavelength of 420 nm. Derivatization was conducted at 70°C using 5.00 mg/mL 3-bromoacetyl coumarin in acetone, with 50 mg of tetrabutylammonium bromide as a catalyst for 150 min. The method has linear ranges of 0.01–0.10 and 0.10–1.00 mg/L, with limits of detection and quantification of 0.0021 and 0.0063 mg/L, respectively. Recoveries ranged from 86.21 to 95.81%, with a relative standard deviation (RSD) below 5%. Additionally, a spiked PFOA concentration of 0.01 mg/L in DTRO-treated leachate effluent following solid-phase extraction was successfully detected with an RSD below 5% using this method.","PeriodicalId":606,"journal":{"name":"Journal of Analytical Chemistry","volume":"80 6","pages":"1062 - 1067"},"PeriodicalIF":1.1,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
