Water and soil contamination represents a global environmental concern that severely affects food and water security, leading to an increased interest in the detection of contaminants in environmental samples. Conventional detection techniques possess high sensitivity; however, they are not able to perform cost-effective, rapid, on-site, and real-time analysis. In this context, biosensors have demonstrated their effectiveness for an accurate, on-site, and real-time detection of different pollutants, including heavy metals, pharmaceutical pollutants, pesticides, microplastics, and biological contaminants. Furthermore, among the various components of a biosensor, the bioreceptors are highly relevant since they are responsible for detecting the contaminants. Therefore, different receptors, including cells, antibodies, aptamers, enzymes, and nanozymes, have been explored in recent times, exhibiting excellent performances. In this review, the most recent advances in each type of biosensor─cell-based, antibody-based, aptamer-based, enzyme-based, and nanozyme-based─are discussed in detail to demonstrate their capacity to detect an ample range of pollutants. Finally, the review compares the different strategies and their current challenges and to suggest possible research directions.

用于监测环境基质中持久性新兴污染物的生物传感器结构

水和土壤污染代表了全球环境问题,严重影响食品和水安全,导致人们对检测环境样品中的污染物越来越感兴趣。常规检测技术灵敏度高;然而,他们无法进行经济高效、快速、现场和实时的分析。在这种情况下,生物传感器已经证明了它们在准确、现场和实时检测不同污染物(包括重金属、药物污染物、杀虫剂、微塑料和生物污染物)方面的有效性。此外,在生物传感器的各种组件中,生物受体具有高度相关性,因为它们负责检测污染物。因此,不同的受体,包括细胞、抗体、适体、酶和纳米酶,近来不断探索,表现出色。在这篇综述中,详细讨论了每种生物传感器(基于细胞、基于抗体、基于适体、基于酶和基于纳米酶)的最新进展,以证明它们检测大量污染物的能力. 最后,综述比较了不同的策略及其当前面临的挑战,并提出了可能的研究方向。
