In addition, they also have excellent data performance such as narrow band gap, large absorption coefficient, large Stokes shift, low self-absorption effect, and luminescence wavelength in the near infrared region. I–III–VI QDs also have a size-dependent luminescence in the visible and near-infrared ranges, and their fluorescence quantum yields can exceed 50% especially when coated with ZnS shells, thus offering great potential for applications in illumination, display, and bioimaging. The review focuses on the synthesis of group I–III–VI QDs, their properties, and applications. In the first part, we discuss the approaches to synthesize these QDs. In the second section, we provide an overview of the applications of I–III–VI QDs in food safety detection, with emphasis on the detection of heavy metal ions, foodborne pathogens, food additives, pesticide, and veterinary drug residues. The final section summarizes the current application prospects of ternary semiconductor QDs.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"1 1","pages":"324 - 336"},"PeriodicalIF":4.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90315111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fabricated electrode’s surface morphology and composition were characterised by scanning electron microscope and transmission electron microscope. The poly(r-o-NBA)/GQDs/CPE showed high electrocatalytic activity towards the oxidation of naproxen (NPX) using cyclic and differential pulse voltammetric methods. The effect of scan rate on the oxidation peak of NPX suggests that the electrode process was typically diffusion-controlled. In addition, the effect of pH reflects the participation of protons in the oxidation process of NPX. The peak current is linearly proportional to the concentration of NPX ranging from 1.0 to 100.0 µM, with the correlation coefficient (R 2), sensitivity, limit of detection (3σ), and limit of quantification (10σ) being 0.9995, 0.419 µA·µM−1·cm−2, 0.672, and 2.241 µM, respectively. Using chronoamperometry, the diffusion coefficient of NPX at the poly(r-o-NBA)/GQDs/CPE was estimated to be 5.36 × 10−6 cm2·s−1. The proposed electrode has good reproducibility, stability, and high selectivity for NPX oxidation. The obtained recovery range (96.7–102.0%) means that the proposed sensor performed satisfactorily when applied for the detection of NPX in its pharmaceutical formulations.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"1 1","pages":"168 - 179"},"PeriodicalIF":4.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80577307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the minor component (TCC) has lower absorptivity, assay of TCC/ETXB tablets presents an analytical challenge. The current study presents two novel methods: first is a micellar electrokinetic capillary chromatography (MEKC). Background electrolyte is borate buffer (40 mM, pH 9.2) containing 30 mM sodium dodecyl sulfate and methanol (ratio 80:20%, v/v), measured at 210 nm. Second is a direct double A max spectrophotometric method; minor component, TCC, is measured directly at its distant λ max (373 nm), at zero absorption of ETXB. Then, a ten-fold dilution step is carried out to eliminate TCC spectral interference and ETXB is determined at its λ max (282 nm). Both drugs’ concentrations disclose obedient linearities at 2–100 μg·mL−1 in MEKC, versus 3–25 and 40–350 μg·mL−1 for TCC and ETXB, respectively, in spectrophotometry. All ICH validation elements have been fulfilled for the developed methods. MEKC and spectrophotometric assays achieve accuracy, precision, selectivity, and robustness to be recommended for industrial quality control routine analysis of TCC/ETXB pills formulated at cited ratios or even higher.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"10 1","pages":"137 - 145"},"PeriodicalIF":4.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72952002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corresponding to antibacterial activity result, antioxidant activity was also higher for AE (75.97% ± 0.5%) compared to remaining extracts (73.77% ± 2.5%, 69.99% ± 0.4%, and 65.24% ± 1.8%) at a concentration of 500 μg·mL−1. Considering both the activities, AE was selected for separation of bioactive molecule by deploying two purification techniques – column chromatography and preparative thin layer chromatography consecutively. After purification, the sample was injected into mass spectrometer and the presence of N-p-coumaroyltyramine and luteolin with excellent antibacterial and antioxidant properties (13.1 ± 2.2 mm and 80.9% ± 2.3%, respectively) were recognised.

Canagliflozin (CGN) was the number one drug, approved by FDA on 29th March 2013 for the treatment of type 2 diabetes mellitus. By totting up to its glucose-lowering effects, it exhibits beneficial effects on the heart and potentially on the kidneys. The study aims to summarize various analytical techniques, such as chromatography, spectrophotometry, and hyphenated techniques, such as Liquid chromatography with tandem mass spectrometry (LC-MS/MS) and Ultra performance liquid chromatography with tandem mass spectrometer (UPLC-MS) for the analysis of CGN. In the proposed work, we have reviewed various analytical methods reported for the estimation of CGN in biological matrices and Pharmaceuticals from various databases like ScienceDirect, Springer, PubMed, Scopus, Taylor & Francis, and Web of Science for the estimation of CGN. Various analytical methods adapted were high-performance liquid chromatography, UPLC, LC-MS/MS, high-performance thin-layer liquid chromatography, Fourier-transform infrared spectroscopy, spectrofluorimetry, and UV spectrophotometry. This current review presented the determination of CGN using various analytical techniques and biological matrices either in single or in combination with other hypoglycemic agents, as per International Conference on Harmonization guidelines. Further, some future trends that can be integrated were also suggested.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"10 1","pages":"287 - 300"},"PeriodicalIF":4.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85987101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
