The material was applied in a dispersive liquid-solid phase extraction (DLSPE) process, enabling the simultaneous adsorption of six PUHs through hydrogen bonding, hydrophobic, and π-π interactions. The extracted PUHs were determined by high performance liquid chromatography. The fabricated porous adsorbent was characterized, and the extraction conditions were optimized. Under optimal conditions, the developed method exhibited linearity from 5.0 to 100 μg L-1 for metoxuron, monuron, chlortoluron and buturon, and from 10 to 100 μg L-1 for isoproturon and monolinuron. The limits of detection were between 1.0 and 3.0 μg L-1. The developed adsorbent was utilized to extract PUHs from rice, cucumber and tomato, achieving recoveries ranging from 70.2 to 96.7 % with RSDs below 9.0 %.

However, current technologies typically rely on observing these structural color changes with the human eye. The human eye has limited color discrimination, thus resulting in insufficient detection accuracy. Meanwhile, viewing angles and ambient lighting can also disrupt observations. Here, we propose a humidity sensor based on surface-functionalized tunable PC grating. The tunable PC grating consists of a 600 nm polystyrene (PS) microsphere PC and a humidity-sensitive hydrogel. As ambient humidity increases, the hydrophilic amide groups (-CONH2) inside the hydrogel interact with the hydrogen bonds between water molecules and triggers hydrogel swelling, exerts interfacial stress on the PS microsphere lattice, thus expanding the lattice spacing of the PS microspheres and causing a red shift in the reflected wavelength. Integrating the surface-functionalized tunable PC grating into a Czerny-Turner (C-T) optical system enables us to directly translate humidity into precise spectral shifts, overcoming the limitations of human eye-based observations. Experimental results demonstrate a strong linear response over the range of 24-94 % relative humidity (RH), as well as excellent repeatability and long-term stability. We provide an innovative solution for high-precision optical humidity sensing.","PeriodicalId":435,"journal":{"name":"Talanta","volume":"296 ","pages":"128521"},"PeriodicalIF":6.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558726","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}

In the absence of Kana, there was no PGM signal recorded because formed nanomagnetic probe was removed by magnetic separation. Conversely, the aptamer could recognize Kana specifically and released cDNA into supernatant. After the addition of sucrose, it was hydrolyzed into glucose by invertase. Detection of Kana was indirectly achieved based on the relationship between glucose concentration and the PGM indication. Furthermore, a miniaturized portable device was constructed by integrating the components using 3D printing technology. Under optimal conditions, rapid detection of Kana within the concentration range of 1-200 nM was achieved, with a detection limit (3σ/k) of 0.28 nM.

In this study, we developed a quinone chemistry-mediated colorimetric strategy for the rapid detection of BAs in meat. BAs such as putrescine undergo a visible colorimetric reaction with 2-methyl-1,4-benzoquinone (MBQ), producing a product with strong UV-visible absorption at 480 nm, enabling specific colorimetric detection of BAs. Structural analysis of the chromogenic product indicated that a Michael addition reaction between BAs and MBQ was the primary mechanism driving the color change. A deep eutectic solvent (DES) was employed to achieve mild and efficient extraction of BAs from samples. Combined with the quinone-mediated colorimetric reaction, we developed a rapid colorimetric detection method for BAs in pork, fish, and shrimp. The results of the colorimetric assay showed good agreement with those obtained from the Kjeldahl-based nitrogen determination method. The developed method does not rely on photosensitive dyes/pigments or structurally complex nanomaterials, offering a simple, efficient, and low-cost strategy for the rapid quantification of BAs and freshness monitoring in meat products.","PeriodicalId":435,"journal":{"name":"Talanta","volume":"296 ","pages":"128527"},"PeriodicalIF":6.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551573","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}

Then, the selectivity experiments indicated that TPA-P4 possessed good selectivity and higher fluorescence enhancement degree for ATP compared with the other probes, and was more suitable for detection of ATP. Further, TPA-P4 was successfully applied to the imaging detection of ATP in mitochondria. Importantly, TPA-P4 could also distinguish between normal liver cells (LO2) and liver cancer cells (HepG2) by imaging ATP, which may show great potential applications in tumor diagnosis.
