Immunoassay technology is widely employed for pesticide detection owing to its high specificity, sensitivity, portability, and cost-effectiveness. This review systematically covers major multiplex immunoassay strategies, including microarray immunoassays, immunochromatographic assays, flow injection immunoassays, and multi-label immunoassays.

This review provides a comprehensive overview of the current approaches used for microplastic analysis, including sampling strategies, sample treatment methods, and detection techniques. To ensure consistency and comparability across studies, standardized protocols for sampling, sample treatment, and detection are urgently needed. Sampling techniques vary depending on the environmental matrix, e.g., water, sediment, biota, and air. Sample treatment strategies, including digestion, oxidation, and enzymatic degradation, are essential for removing naturally occurring organic contaminants while preserving microplastic integrity. Density separation is often applied to remove the inorganic part of the matrix, and the final treatment step often involves a volume reduction method such as filtration to concentrate microplastics. However, these processes must be carefully optimized to minimize sample loss, degradation, and contamination from plastic apparatus. The review discusses the application of spectroscopic methods such as Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy that remain the most widely used techniques, while also describing emerging methods such as electrochemical studies, hyperspectral imaging, and terahertz spectroscopy. Mass spectrometry (MS) coupled approaches such as gas chromatography (GC-MS), pyrolysis GC-MS, liquid chromatography (LC-MS), and inductively coupled plasma (ICP-MS) that enable quantification are also covered in the following review.</div></div>","PeriodicalId":439,"journal":{"name":"Trends in Analytical Chemistry","volume":"197 ","pages":"Article 118682"},"PeriodicalIF":12.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146049000","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}
