Furthermore, due to their nano size and safe travel in extracellular fluids, exosomes have been investigated as natural drug delivery systems, delivering cargo to destined cells with excellent specificity and efficiency, and crossing the blood–brain barrier. This necessitates the isolation and detection of exosomes. However, numerous exosome isolation techniques are available, including ultracentrifugation, size-based chromatography, polymer precipitation, microfluidics, and immunoaffinity-based isolation, with the downfalls of non-specificity and lower cost-effectiveness. This article introduces an immunoaffinity-based detection of exosomes using targeted anti-exosome antibodies raised in chickens due to its economic and commercial viability. The current study is unique in that it identified a specific antigenic region on exosomal surface tetraspanins (CD9, CD63, CD81) and constructed a multiple antigenic peptide dendrimer for making a small peptide as an immunogen without the use of a carrier protein. The antigenic region selection is critical to the study because it determines the efficiency of antibodies for exosome capture. This technique was validated using enzyme-linked immunosorbent assay in various biological fluids such as serum, urine, milk, plasma, and blood due to its numerous advantages including high sensitivity, specificity, handling multiple samples at once, requiring a small sample amount, and no purification as an antigen. In light of this technique, it is a useful tool for clinical monitoring of the patient’s biological conditions.

NDIR sensors offer significant advantages in methane sensing, including high sensitivity, selectivity, and long-term stability. The underlying principles of NDIR sensors involve measuring the absorption of infrared radiation by the target gas molecules, leading to precise and reliable methane concentration measurements. Advanced signal processing techniques, such as single-frequency filtering and wavelet filtering algorithms, have been explored to improve the performance of the sensor by reducing noise, enhancing the signal-to-noise ratio, and achieving more accurate results. In the context of multi-gas detection, NDIR sensors face challenges due to overlapping absorption spectra. However, various solutions, including narrow-band optical bandpass filters, gas filter correlation techniques, and machine learning algorithms, have been proposed to address these issues effectively. This study delves into specific applications of NDIR sensors in various industries, such as coal mines, wastewater treatment plants, and agriculture. In these settings, NDIR sensors have demonstrated their reliability, accuracy, and real-time monitoring capabilities, contributing to environmental protection, safety, and energy recovery. Furthermore, the anticipated future trends and developments in NDIR methane detection technology are explored, including increased miniaturization, integration with artificial intelligence, improvements in power efficiency, and the development of multi-gas NDIR sensors. These advancements are expected to further enhance the capabilities and widespread adoption of NDIR sensors in methane detection applications.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134980954","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}

One of the key factors affecting the environmental sustainability of analytical methods is the choice of solvent. In this particular study, a two-factor, three-level response surface design was employed to develop an environmentally friendly chromatographic technique for a mixture of metformin, glimepiride, and pioglitazone. Ethanol, which is known to be harmless to the environment, was chosen as the organic modifier in the mobile phase. The separation of the mixture was achieved using a phosphate buffer solution (pH 3) mixed with ethanol (30:70 v/v). The linearity of the developed method covered a concentration of metformin of 10–120 µg·mL −1 with a correlation coefficient of 0.9998, glimepiride of 0.1–20 µg·mL −1 with a correlation coefficient of 0.9997, and pioglitazone of 1–50 µg·mL −1 with a correlation coefficient of 0.9999. To evaluate the environmental friendliness of the developed method, two assessment tools were employed: The Analytical GREEnness metric and Green Analytical Procedure Index. The results revealed that the developed method performed exceptionally well in terms of its eco-friendliness. Furthermore, the developed method was compared to other reported methods in terms of both accuracy and environmental sustainability. The results demonstrated that the developed method serves as an excellent alternative to well-established techniques for the separation and quantification of the analyzed mixture. Overall, this study highlights the importance of integrating green chemistry principles into analytical chemistry practices.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135508720","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}

In this study, two different chromatographic methods were developed for the determination of APX in pharmaceutical products. In the first method, an Agilent C18 column (250 mm × 4.6 mm, 5 μm) was used, and the temperature was kept constant at 30°C. The mobile phase was chosen to be 0.1% trifluoroacetic acid solution and acetonitrile (65:35, v/v), and isocratic elution was applied. The flow rate of the mobile phase was found to be 1.0 mL·min−1 and the injection volume was 20 µL. The detection was carried out at a wavelength of 276 nm using a UV detector. In the second method, ethanol was used as an organic modifier. The only difference between these methods was the organic modifier. All other conditions of the methods were the same. Both chromatographic methods were validated in accordance with ICH guidelines for various parameters such as selectivity, linearity, accuracy, precision, detection and quantification limit, and robustness. The determination coefficients of chromatographic methods were greater than 0.999 in the concentration range of 5–30 mg·mL−1 of APX. Later, these chromatographic methods were applied to tablet formulations. Comparison of the obtained results in terms of mean was made using Student’s (t) test, and comparisons in terms of standard deviations were made using the Fisher (F) test. It was observed that there was no significant difference between these methods. These two methods were then evaluated using AGREE-Analytical greenness metric software. The chromatographic method using ethanol as an organic modifier has been proposed as an excellent eco-friendly and analyst-friendly alternative for the determination of APX in pharmaceutical formulations.

Worldwide awareness of our planet and ecological hazards have raised the shades of green and sustainable chemistry in pure or formulated API assays. The Green Analytical Procedure Index (GAPI) is instant five pentagrams for evaluating the greenness of each step in the developed analytical procedure, in discriminative colors: green, yellow, and red. In the present study, GAPI is applied to assess three novel direct analytical methods: spectrophotometric, fluorimetric, and high-performance thin-layer chromatography (HPTLC) for remdesivir (RDV) quantitation, both in bulk and pharmaceutical vials. Furthermore, a comparative green level calculated GAPI study has been assembled for the proposed methods versus the previously reported methods, for RDV assay, of similar techniques. Spectrophotometric direct A max method at 240 nm, fluorimetric emission at 404 nm upon excitation at 275 nm as well as the HPTLC densitometric measurement using ethanol and distilled water (7:3, v/v) as mobile phase, all three methodologies are developed, optimized, and fully validated for RDV quantitation. They have been applied to assay RDV pharmaceutical vials and results are compared together with a one-way ANOVA test. Satisfactory recoveries and nano-level sensitivities in addition to the least standard deviations encourage the use of developed methods for routine analysis in quality control laboratories. Their promising greenness profile satisfies the beliefs of ecological sustainability of Green Agenda 2030.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135311306","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}

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.
