Conventional treatment approaches often fall short due to high operational costs, potential secondary pollution, and limited effectiveness against emerging pollutants. In response, green and natural materials have emerged as attractive alternatives for both contaminant removal and water quality monitoring, offering advantages such as biodegradability, ecological safety, cost-efficiency, and wide availability. This review provides a detailed overview of recent advancements in utilizing plant-based adsorbents, agricultural and industrial bio-wastes, natural polymers, clays, algae, microbial biomass, and eco-friendly nanomaterials for water purification. It explores key removal strategies including adsorption, photocatalytic degradation, membrane filtration, bio-based coagulation-flocculation, and bioremediation, demonstrating their effectiveness in targeting heavy metals, organic pollutants, biological contaminants, microplastics, and newly recognized environmental toxins. Furthermore, the integration of these natural materials into portable, low-cost sensing technologies—such as colorimetric, electrochemical, and fluorescent biosensors—is examined, offering innovative tools for real-time contaminant detection. The review also highlights emerging hybrid systems that combine green nanomaterials with biochar, biopolymers, and metal-based nanoparticles to enhance contaminant removal and multifunctional performance. Key practical considerations, including scalability, material uniformity, environmental impacts, biodegradability, and regulatory challenges, are addressed. A life cycle assessment (LCA) perspective is incorporated to compare the sustainability of these green alternatives with conventional materials. The article concludes by outlining future research opportunities focused on hybrid technologies, smart sensing integration, and circular economy frameworks to support scalable, sustainable, and decentralized water purification solutions.</div></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"48 ","pages":"Article e00285"},"PeriodicalIF":13.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Natural enzymes, as efficient catalysts produced in living organisms, can be applied to the detection and sensing of pollutants through their mediated enzymatic reactions. However, the poor environmental stability, complex purification techniques, and high costs of natural enzymes have limited their large-scale application in environmental analysis. Nanozymes, as a class of nanomaterials with enzyme-like activity, are characterized by high catalytic activity, good stability, low cost, and easy production and preparation. Most nanozymes use transition metals as catalytic active sites. Since copper has multiple oxidation states, nanozymes with copper as the active center typically exhibit multiple activities, particularly some copper-based nanozymes that possess oxidase-like activity, whose catalytic action relies on oxygen. This characteristic has enabled their broader application in environmental analysis (e.g., rapid detection and identification of environmental pollutants). This review discusses the classification of enzyme-like activities of copper-based nanozymes and their design strategies, composition types, and various applications in the field of environmental analysis (rapid detection and identification of environmental pollutants) based mainly on the research of copper-based nanozymes for the analysis of environmental pollutants in the last three years, and summarizes the current status of copper-based nanozymes in environmental analysis (their effectiveness in detecting and identifying environmental pollutants), challenges (low sensitivity, poor selectivity, lack of rational design), and future trends (integration with electrocatalysis, molecular imprinting technology, and rational design based on target substance characteristics). We link the activity of copper-based nanozymes with their corresponding design strategies and discuss approaches to yield copper-based nanozymes with a range of activities. The interactions between the target substances and the signal output generated by copper-based nanozymes are summarized.
