The present investigation discusses the plant-mediated synthesis of CuO/ZnO (CuZn10 and CuZn20 for 10% and 20% of CuO stoichiometry, respectively) bimetallic nanocomposites employing <i>Lagerstroemia Speciosa</i> flower extract and its application as a photocatalyst. The structural and optical characteristics, chemical composition, functional groups, and morphology of the synthesized CuO/ZnO bimetallic nanoparticles were investigated using XRD, UV-visible spectroscopy, EDS, SEM, FTIR, and BET techniques. The maximum absorption peaks were observed at 359 nm for CuZn20 and at 364 nm for CuZn10. The band gaps were estimated to be 2.92 eV and 2.82 eV, respectively. The comparative photocatalytic degradation efficiency of the two binary composites was evaluated for the materials. In 90 min of exposure to sunlight, the CuZn20 bimetallic nanoparticles showed better catalytic efficiency than the CuZn10 bimetallic nanoparticles against Methylene Blue (MB). Additionally, the synthesized nanocomposites showed excellent antibacterial activity against <i>L. monocytogenes</i> and <i>S. typhi</i>.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"37 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237214","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}

The key innovation lies in the design of highly specific primers targeting Sus scrofa mitochondrial DNA, ensuring accurate identification with minimal cross-reactivity. The LAMP technique was selected for its rapid amplification, isothermal operation, and simplified equipment requirements, making it suitable for on-site applications and reducing overall costs. Optimization of reaction conditions enabled reliable DNA amplification at 63°C within 60 minutes. The progress of the amplification was monitored in real time by measuring turbidity, while successful DNA synthesis was further confirmed by gel electrophoresis. For sensitive detection and quantification, an electrochemical DNA biosensor was integrated into the workflow. This biosensor utilizes a silicon nanowire–platinum nanoparticle–modified screen-printed carbon electrode and ferrocenylnaphthalene diimide as a dsDNA intercalator, enabling precise, real-time monitoring of the LAMP reaction. The optimized assay achieved a detection limit of 175.2 ng/μL, demonstrating high sensitivity for low-level porcine DNA detection. Specificity was validated across various meat sources and processed foods, with no false positives observed. The biosensor-based method also successfully detected porcine DNA in mixed meat samples, highlighting its strong potential for practical use in food authenticity testing and regulatory compliance.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"37 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10876-026-03041-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Copper-based nanomaterials, especially bimetallic silver-copper (AgCu) nanoparticles supported on silica (SiO₂), offer promising alternatives due to enhanced antimicrobial performance and controlled ion release. This study investigates how the sub-microstructure of AgCu nanoparticles affects their antimicrobial activity.

Tests on marine microbial communities showed that the heterophase NC exhibits stronger antibacterial activity at a lower concentration (250 µg mL^− 1) than the homophase NC (500 µg⋅mL^− 1), attributed to higher metal ion release and increased reactive oxygen species generation.
