Copper nanoparticles (CuNPs) are tiny materials with special features such as high electric conductivity, catalytic activity, antimicrobial activity, and optical activity. Published reports demonstrate their utilization in various fields, including biomedical, agricultural, environmental, wastewater treatment, and sensor fields. CuNPs can be produced utilizing traditional procedures; nevertheless, such procedures have restrictions like excessive consumption of energy, low production yields, and the utilization of detrimental substances. Thus, the adoption of environmentally approachable "green" approaches for copper nanoparticle synthesis is gaining popularity. These approaches involve employing plants, bacteria, and fungi. Nonetheless, there is a scarcity of data regarding the application of microbial bioflocculants in the synthesis of copper NPs. Therefore, this review emphasizes copper NP production using microbial flocculants, which offer economic benefits and are sustainable and harmless. The review also provides a characterization of the synthesized copper nanoparticles, employing numerous analytical tools to determine their compositional, morphological, and topographical features. It focuses on scientific advances from January 2015 to December 2023 and emphasizes the use of synthesized copper NPs in wastewater treatment.
铜纳米颗粒（CuNPs）是具有特殊特性的微小材料，如高导电性、催化活性、抗菌活性和光学活性。已发表的报告展示了它们在包括生物医学、农业、环境、废水处理和传感器领域在内的各个领域的应用。CuNPs可以通过传统方法制备；然而，这些方法存在诸如能源消耗过多、产量低以及使用有害物质等限制。因此，采用环境友好型的“绿色”方法来合成铜纳米颗粒越来越受欢迎。这些方法涉及使用植物、细菌和真菌。尽管如此，关于微生物生物絮凝剂在铜纳米颗粒合成中的应用的数据却很匮乏。因此，本综述着重介绍了使用微生物絮凝剂生产铜纳米颗粒，这种方法具有经济效益且可持续、无害。该综述还对合成的铜纳米颗粒进行了表征，使用了多种分析工具来确定其组成、形态和拓扑特征。它聚焦于2015年1月至2023年12月的科学进展，并强调了合成的铜纳米颗粒在废水处理中的应用。
