MOF materials, because of their unique structures and properties, such as controllable pore size, large surface area, excellent catalytic activity, and high density of active sites, are applied in electrochemical sensors systems for the sensitive, quick, and low-cost detection of multiple analytes. MOFs, with their high specific surface area, controllable shape, and adjustable pore volume, will provide strong interaction with compounds via abundant functional groups, leading to increased selectivity for electrochemical determination of a wide range of compounds. In this review, the structure, synthesis methods, characterization, and the applications of MOFs in recent years as sensing material in fabricating sensors for detecting drugs, pesticides, heavy metals, food additives, and other contaminants are summarized, compared, and discussed. Also, MOFs were used in numerous antibacterial application areas due to their long-term release pore volume, capability, and stretch ability when integrated with a wide range of compounds and/or substances (including nanostructures, phytochemicals, antibiotics, and polymers).

The elucidation of complex RNA‒protein interaction patterns and specific binding sites has been the subject of intensive research in recent years. However, large-scale RNA‒protein binding site (RBS) identification remains an urgent issue due to the lack of broad and unbiased RBP enrichment methods. In this study, a novel strategy for RBS identification was developed by using a psoralen probe (PP) for large-scale RBP enrichment. A total of 1957 high-confidence RBPs with good reproducibility were identified via mass spectrometry. A total of 1783 protein groups (91.1%) were previously annotated as RBPs. To identify RBSs, the enriched RBPs were treated with two different methods: digestion via ribonucleases (RNases) or hydrofluoric acid (HF). A total of 448 high-confidence RBSs were identified by using the former strategy, and 1301 high-confidence RBSs were identified by using the latter method. By comparing the identification results of cross-linking sites in both methods, it was observed that the binding of RNA to RBP was less likely to occur on acidic amino acids. Furthermore, the HF method can identify RBS in a more unbiased manner than the RNase method. The above mentioned results suggest the potential of both methods for large-scale RBS identification.</p></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"51 8","pages":"Article 100291"},"PeriodicalIF":1.2,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3198713","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}

Ion dissociation is typically performed by tandem mass spectrometry, in which the overall molecular weight is determined during the first stage and the protein sequence and structure are obtained by dissociation during the second stage. However, conventional dissociation methods have some disadvantages, such as insufficient dissociation efficiency, and low product signals and varieties. Ultraviolet photodissociation (UVPD) is a rapid, efficient, and practical dissociation method for protein analysis, which excites the biomolecule skeleton and then directly excites the molecules, forming the excited states within microseconds. Although the development of mass spectrometer platforms coupled with UVPD has been reported to date, most of these studies have focused on the application of UVPD in mass spectrometry (MS). Discussions on the experimental setup for UVPD lasers, including the trigger process of the ultraviolet (UV) laser, the timing sequence of the entire dissociation and detection process, and their influence on dissociation, are limited. Therefore, an instrument platform was developed with a linear ion-trap mass spectrometer and an excimer laser to achieve UVPD by adjusting the laser trigger signal. The platform dissociated the disulfide bond of the amino acid sequence ARACAKA-ECG into two characteristic valence states (<em>m/z</em> = 498 and 332), and their highest intensities were obtained by optimizing the experimental conditions of the platform. The dissociation results of UVPD showed the characteristic peaks of ARACAKA (<em>m/z</em> 345) that were produced by disulfide bond cleavage, but these peaks were not detected by collision-induced dissociation (CID). Therefore, it was confirmed that the developed platform realized UVPD of the disulfide bond of the amino acid sequence of the polypeptide. Moreover, the developed platform provides a reference for the implementation of UVPD for peptide sequencing.</p></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"51 8","pages":"Article 100285"},"PeriodicalIF":1.2,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1553842","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}

While miRNAs are characterized by short sequence length, large single cell copy number variation, low abundance in vivo, and high homologous sequence similarity. The development of miRNA detection methods with high sensitivity, good selectivity and low cost is the key to study the function of miRNA. In this article, a method combining isothermal chain replacement amplification and G-quadruplex (G4) specific detection is developed for highly specific and sensitive detection of miRNA. By designing proper DNA sequences, a three-stranded DNA complex was formed and produced a lot of G4 structure sequences, which can be stained by specific fluorescence dye and quantified. In the experiment, the fluorescence dye shows extremely high specificity, which brings excellent signal discrimination, so that the target miRNAs can be accurately detected. Experiments under high background noise also verified this method is highly selective for target miRNAs. This method holds great imagination in expanding the detection methods to more platforms, such as nanopore sensors, because it alters the secondary structure of DNA sequences.</p></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"51 8","pages":"Article 100292"},"PeriodicalIF":1.2,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1894804","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}

In view of this, one fluorescent probe 3HF-Br, which can produce ratio signals of absorption spectrum and emission spectrum for the detection of N₂H₄, was constructed in this work. Based on the sensing mechanism of S_N2 nucleophilic substitution - cyclization - elimination, 3HF-Br has sensitive spectral response to N₂H₄ via ESIPT effect. After the reaction, the highest emission peak of fluorescence spectrum shifted from 501 nm (cyan blue) to 561 nm (bright green), with the ratio signal (<em>I</em>_561/501 _nm) increased by about 10 time. For N₂H₄ detection, 3HF-Br has high sensitivity and low detection limit (0.184 µM), and the maximum ratio reached at 17 min. In addition, it also showed high selectivity for the detection and is not disturbed by other nucleophilic substances. It is worth mentioning that under the ratio signal, the probe 3HF-Br can effectively monitor and image N₂H₄ not only at the cellular level but also in zebrafish.
