Herein, we developed a target-on fluorescence assay, termed LIGHT-CDS, for the label-free and amplification-free detection of polyvinyl chloride (PVC) and polystyrene (PS) microplastics. The assay integrates a microplastic-responsive T-DNA release module with a Cas12a–DNAzyme–Spinach light-up circuit. Binding of PVC or PS to an aptamer-locked T-DNA complex releases T-DNA and activates Cas12a trans-cleavage. Activated Cas12a subsequently cleaves and inactivates the 10–23 DNAzyme, thereby protecting Baby Spinach RNA from degradation and enabling fluorescence generation through DFHBI-1T binding. Under optimized conditions, LIGHT-CDS generated concentration-dependent responses to PVC and PS over a tested calibration interval of 0.1–500μg/mL, with detection limits of 96.7 and 139.3ng/mL, respectively. The assay exhibited good selectivity against common non-target particles, maintained reliable responses in mixed-particle systems, and retained approximately 90% of its initial response after 21 days of storage. In spiked tap-water and river-water samples, PVC recoveries ranged from 94.3% to 115.3%, with relative standard deviations not exceeding 7.1%. These results establish LIGHT-CDS as a simple, programmable, and labeled-probe-free analytical platform for PVC/PS microplastic screening in water matrices and support further validation toward food and beverage applications.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"159 ","pages":"Article 109517"},"PeriodicalIF":5.3,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149006373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we developed an activity-guided online HPLC-pancreatic lipase recognition system to simultaneously recognize and monitor active chromatographic peaks in <em>Rubus irritans</em> fruit extracts. Four compounds, namely cinnamic acid (1), 5-hydroxy-6,7,3′,4′-tetramethoxyflavone (2), 1-hydroxy-2,3,5-trimethoxyxanthone (3), and salvigenin (4), were first isolated from these fruits via medium- and high-pressure liquid chromatography. <em>In vitro</em> assays showed that all inhibited pancreatic lipase, with IC₅₀ values of 444.90 ± 0.19, 142.64 ± 0.93, 168.70 ± 0.64, and 118.84 ± 0.89 μM, respectively. Salvigenin (4) acted via reversible competitive inhibition. Molecular docking revealed the binding modes of the four compounds in the pancreatic lipase active site, with salvigenin exhibiting the lowest binding energy (-7.3 kcal/mol), followed by compounds 1–3 (-5.4, −6.8, and −6.9 kcal/mol). DFT calculations indicated that salvigenin had a smaller HOMO-LUMO gap and a higher dipole moment, suggesting favorable reactivity.

The HFD was formulated by increasing soybean oil from 1 % to 7 %, replacing corn and wheat bran.

Metabolomics indicated that amino acid metabolism and lipid-stress shifted in PEM and oxidative-stress was remodeled in SOL, implicating linoleic/unsaturated-fatty-acid pathways.
