Furthermore, the development of a multi-organelle viscosity fluorescent probe that is capable of visualizing multiple disease models (liver injury and tumor) poses severe deficiency and remains a great challenge. Herein, for the first time, we developed a novel triple-targeting fluorescence probe (membranes, mitochondria and nuclei, named MMN), which can initially accumulate on the cell membranes, then migrate to mitochondria, and ultimately binds to the nuclei through DNA interaction. MMN consisted of a donor-π-acceptor (D-π-A) structure and extended double bonds bridging rotor, which exhibited sensitive response to viscosity and strong fluorescence intensity. The twisted intramolecular charge transfer (TICT) of MMN was suppressed with an increase in viscosity, accompanied by a significant enhancement of red fluorescence signal with emission wavelength of 585 nm. Cascade imaging of mitochondria and nuclei with MMN allowed real-time monitoring and visualization of mitochondrial status within live cells. Using MMN, we have demonstrated the visualization of liver injury and tumor via mitochondrial viscosity imaging. Therefore, MMN holds significance for studies related to mitochondrial injury and the prevention and treatment of associated diseases.</div></div>","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"434 ","pages":"Article 137614"},"PeriodicalIF":8.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635644","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}

This research introduces a convenient and rapid one-pot RPA-CRISPR/Cas13a diagnostic system that is both sensitive and specific for the identification of HAdV DNA. The system incorporates two detection modalities: RPA-CRISPR/Cas13a-Flu for fluorescence-based detection and RPA-CRISPR/Cas13a-LFS for visual detection. The sensitivity of the RPA-CRISPR/Cas13a-Flu method was measured at 5 copies per reaction, while the RPA-CRISPR/Cas13a-LFS demonstrated a sensitivity of 50 copies per reaction, with both methods achieving 100 % specificity. Validation against 175 clinical samples indicated that the RPA-CRISPR/Cas13a-Flu had a sensitivity of 95.95 % (95 % CI 88.75–98.61), specificity of 100 % (96.34–100), accuracy of 98.29 % (95.08–99.42), and a Kappa coefficient of 0.965 when compared to traditional qPCR methods.

The accuracy and precision of the proposed method have been proven for the working range of 0.5–33 mg·kg<sup>−1</sup>, using GC-MS as a reference method meeting the requirement of the European Union regulations. The robustness of the proposed method was confirmed by investigating possible variations in relative humidity under out-of-laboratory conditions. Moreover, it was possible to determine ageing equations for sensitivity correction during sensor usage, which reduce the need for sensor recalibration. The ageing equations of sensors and the determination of the relationship between the concentration of hexane injected in the oil and extracted in the headspace were determined using a computer-controlled gas mixing system. The oil matrix effect was found to be negligible for oils meeting the required quality parameters. The developed sensor-based method allows for monitoring residual hexane in edible oils, both during the oil extraction process and in the safety control of the final product.

However, conventional designs face a trade-off between achieving high Q-factor and high sensitivity. To overcome this limitation, this paper proposes a novel reflection-type GMR metasurface that integrates a secondary grating array with a metallic reflector. Unlike traditional transmission-type monolayer grating structures, our design employs a metal reflector positioned between the substrate and the waveguide, which confines the localized electromagnetic fields within the waveguide and prevents their leakage into the substrate. Simultaneously, the secondary grating achieves large spatial overlap between the analyte and the localized electric fields. As a result, under transverse electric (TE)-polarized normal incidence, our metasurface exhibits a pronounced resonance dip with a narrow linewidth, leading to significantly high biochemical sensing sensitivity and high Q-factor. Furthermore, the proposed metasurface demonstrates a measured sensitivity of 420.33 nm/RIU and a specific detection of the biomarker cytokeratin 8 and 18 (CK8/18) associated with gastric cancer cells. Compared with conventional GMR sensor designs, our approach offers not only superior sensing performance but also practical fabrication advantages due to its low aspect ratio grating structure. Therefore, this first proposed reflection-type GMR secondary grating structure provides a promising pathway for the development of high-sensitivity, high Q-factor metasurfaces, with high-precision, high-resolution, high signal-to-noise ratio sensing applications in clinical diagnostics.</div></div>","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"434 ","pages":"Article 137609"},"PeriodicalIF":8.0,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635645","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}
