Hence, the development of a rapid, accurate, and sensitive detection technology has become a pivotal aspect of ensuring control standards. In this study, we introduce the UIO66 and two defective dichloroacetic acid@UIO66 (DCA@UIO66, DU) metal-organic framework nanoparticles, named DU1 and DU2, characterized by different defect levels. It is noteworthy that DU1 exhibits superior DNA sensing capability compared to UIO66 and DU2. With a fluorescence quenching efficiency of 92.66 % and a recovery efficiency of 1256.75 %, DU1 demonstrates the substantial potential in the detection field. Furthermore, we employ cascade isothermal amplification to assist DU1-mediated fluorescence sensors in detecting AFB1. AFB1 is efficiently identified through an aptamer competition process facilitated by magnetic nanoparticles, which initiates the exponential amplification triggered rolling circle amplification reaction, and converts trace amounts of toxin signal into a large number of long single-stranded DNA molecules. Upon recognition of the amplification product by the fluorescent probe on DU1, a more stable double-stranded DNA is formed and leaves the surface of DU1, leading to a significant change in fluorescence intensity. This method exhibits acceptable sensitivity, with a detection limit of 0.09 pg mL^-1 and a wide detection range spanning from 0.2 pg mL^-1 to 20 pg mL^-1. Additionally, this assay exhibits satisfactory specificity and high accuracy in practical sample applications.

This study introduces a dual-signal fluorescence system, termed Fe₃O₄@Au@PEG@P1+MOF@P₂, that integrates magnetic separation of Fe₃O₄@Au with NH₂-MIL-88 (MOF) catalysis. Initially, the specimen (T1/T2) facilitated the formation of a specific complex (Fe₃O₄@Au@PEG@P1+T1/T2) with Fe₃O₄@Au@PEG@P1. The subsequent addition of Hoechst-33258 produced a robust fluorescence signal at 460 nm, enabling the identification of mutations in the first gene regions. Following this, MOF@P₂ was introduced to activate the catalyst through P2 pairing with T2. The complex Fe₃O₄@Au@PEG@P1+T1/T2+P2+Hoechst-33258 was subsequently isolated using an external magnetic field. Upon adding OPD, fluorescent DAP was detected at 560 nm, allowing for the identification of mutations in the second gene regions. The research demonstrated that the variation in fluorescence signals increased with a higher number of base substitutions and deletion mutations, with deletion mutations resulting in a notably greater alteration rate compared to substitution mutations. Interestingly, triple base substitution mutations, characterized by lower clustering of non-continuous mutations, produced a more pronounced change in fluorescence signal than did a higher clustering of continuous mutations (codon mutations). This single-step methodology effectively differentiates among the number and types of mutations across multiple gene regions while assessing the degree of mutation clustering. Overall, this technology significantly enhances the current capabilities for detecting fine structural mutations in genes. Furthermore, the approach exhibits high sensitivity in detecting concentrations of T1 and T2 ranging from 10^-15 M to 10^-9 M, with detection limits of 0.19 fM and 0.24 fM, even in 5 % serum samples.</p>","PeriodicalId":435,"journal":{"name":"Talanta","volume":"285 ","pages":"127384"},"PeriodicalIF":5.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a copper-based fluorescent nanozyme (Cu-BH) synthesized with dual-ligand, integrating fluorescence and oxidase-mimic into one spherical nanomaterial, was used firstly to establish a ratiometric approach for visual detection of thiophanate methyl (TM). Cu-BH possesses excellent oxidase-like activities, triggering the oxidation of colorless o-phenylenediamine (OPD) into yellow luminescent products (oxOPD, λem = 564 nm). Besides, the ligand of 2-amino-1,4-benzene-dicarboxylic acid imparts Cu-BH blue fluorescence (λem = 425 nm), which is quenched by oxOPD via inner filtration effect (IFE). The introduction of TM can prevent not only the oxidase-like activity remarkably but also the intrinsic luminescence of Cu-BH slightly because of the complexation of TM with Cu²⁺. As a result, the fluorescence intensity at 564 nm and 425 nm presents a significant decrease and a slight increase, respectively, producing a ratiometric fluorescent signal (F₄₂₅/F₅₆₄). Therefore, a novel ratiometric fluorescent strategy has been proposed to detect TM ranging from 0.1 to 100 μM with detection limit of 0.03 μM (S/N = 3).

Therefore, a new red fluorescent nano-probe was needed to rapidly and accurately detected GSH within the biological matrix. Herein, red carbon dots (R-CDs) synthesized via hydrothermal method using N-(4-amino phenyl) acetamide and 4-Bromo-1,2-diaminobenzene as precursors offer enhanced fluorescence that could be quenched by MnO₂ nanosheets (MnO₂ NS) and restored by GSH. By combining R-CDs with the AS1411 aptamer and using rolling circle amplification, a multivalent aptamer modified R-CDs assembly (Assembly@R-CDs) was created for swift cancer cell targeting. Compared to monomeric aptamer, such multivalent aptamers exhibited higher affinity and selectivity, thereby enhancing the specificity and sensitivity of detection. After the fluorescence of the multivalent assembly was quenched by MnO₂ NS (Assembly@R-CDs@MnO₂ NS), it could be restored when targeting cancer cells, which could realize the distinction between normal cells and cancer cells. The experiment showed that 4T1 cancer cells took up more Assembly@R-CDs@MnO₂ NS than L929 normal cells and generated stronger fluorescence, indicating the high selectivity for cancer cell detection.

However, variations in particle size distribution negatively affect the diffuse reflectance of NIRS and the fluorescence signal intensities of XRF, leading to decreased accuracy and repeatability in predictions. To address this issue, this study innovatively proposes a particle size correction method that integrates image processing and deep learning. The method first captures micro-images of the coal sample surface using a microscope camera and employs the Segment Anything Model (SAM) for binarization to represent particle size distribution. Subsequently, a Spatial Transformer Network (STN) is applied for geometric correction, followed by feature extraction using a Convolutional Neural Network (CNN) to establish a correlation model between particle size distribution and ash measurement errors. In experiments involving 56 coal samples, including 48 at 0.2 mm for the standard ash prediction model and 8 within a 0∼1 mm range for correction, the results showed significant improvements: standard deviation (SD), mean absolute error (MAE), and root mean square error of prediction (RMSEP) decreased from 0.321%, 0.317%, and 0.335% to 0.229%, 0.225%, and 0.257%, respectively.
