Developing sensitive, rapid, and cost-effective detection methods is crucial for ensuring food safety and environmental protection. Colorimetric and fluorescent optical nanosensors leveraging localized surface plasmon resonance (LSPR) in plasmonic nanoparticles, including gold, silver, and copper nanostructures, have emerged as promising tools for OPP detection due to their rapid response, high sensitivity, selectivity, and real-time monitoring capabilities. Colorimetric nanosensors leverage LSPR-induced visible color shifts resulting from nanoparticle aggregation, anti-aggregation, enzymatic inhibition, nanoparticle growth, or etching-based mechanisms. In contrast, fluorescent nanosensors utilize plasmonic interactions to enhance or quench fluorescence signals. This review critically examines recent advancements in LSPR-based nanosensors, their detection mechanisms, advantages, and limitations. Moreover, the potential integration of these sensors with emerging technologies, such as machine learning, smartphone-based imaging, and paper-based platforms, is explored to enhance their field applicability. Addressing existing challenges, including sensor stability, selectivity, and large-scale production, will be key to developing next-generation pesticide detection systems with real-world applications in food safety and environmental monitoring.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"144 ","pages":"Article 107653"},"PeriodicalIF":4.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Delayed luminescence (DL) can reflect the internal changes caused by processing by detecting the photon emission characteristics of a substance. It has been applied to the quality assessment of crops and vegetables. We combined DL detection and chemometric methods to reveal the relationship between the internal changes and DL characteristics of RG with different steaming times. We also evaluated the functional properties of RG to compare the quality differences between samples. The results show decreasing DL decay curves and parameters (I0, T, Tau) with prolonged steaming. Chemometric and DL correlation analysis showed that there is a strong correlation between rare ginsenosides (Rg3, Rg5, Rk1) and DL parameters. Moreover, bioactivity test results showed that the three rare ginsenosides closely related to DL parameters may have more comprehensive immunomodulatory functions. Thus, DL effectively discriminates RG processed for different durations and helps characterizes potent rare ginsenosides.
