Micropollutants contamination and global warming are critical environmental issues that require urgent attention due to natural and anthropogenic activities posing serious threats to human health and ecosystems. However, traditional technologies, such as adsorption, precipitation, biodegradation, and membrane separation, are facing challenges of low utilization efficiency of oxidants, poor selectivity, and complex in-situ monitoring operations. To address these technical bottlenecks, nanobiohybrids, synthesized by interfacing the nanomaterials and biosystems, have recently emerged as eco-friendly technologies. In this review, we summarize the synthesis approaches of nanobiohybrids and their utilization as emerging environmental technologies for addressing environmental problems. Studies demonstrate that enzymes, cells, and living plants can be integrated with a wide range of nanomaterials including reticular frameworks, semiconductor nanoparticles and single-walled carbon nanotubes. Moreover, nanobiohybrids demonstrate excellent performance for micropollutant removal, carbon dioxide conversion, and sensing of toxic metal ions and organic micropollutants. Therefore, nanobiohybrids are expected to be environmental friendly, efficient, and cost-effective techniques for addressing environmental micropollutants issues and mitigating global warming, benefiting both humans and ecosystems alike.
微污染物的污染和全球变暖是两个至关重要的环境问题，由于自然和人为活动对人类健康和生态系统构成了严重威胁，因此需要引起紧急关注。然而，传统的技术，如吸附、沉淀、生物降解和膜分离，面临着氧化剂利用率低、选择性差以及原位监测操作复杂等技术瓶颈。为了解决这些技术难题，纳米生物杂化材料作为一种环保技术，由纳米材料和生物系统界面合成而出现。在这篇综述中，我们总结了纳米生物杂化材料的合成方法及其作为新兴环境技术在解决环境问题中的应用。研究表明，酶、细胞和活体植物可以与各种纳米材料（包括网状框架、半导体纳米粒子和单壁碳纳米管）结合。此外，纳米生物杂化材料在去除微污染物、转化二氧化碳以及检测有毒金属离子和有机微污染物方面表现出优异的性能。因此，纳米生物杂化材料有望成为解决环境微污染物问题和缓解全球变暖的环保、高效且具有成本效益的技术，造福人类和生态系统。
