Nanoparticles synthesis under green conditions has been performed using natural resources to diminish the use of toxic chemicals. For instance, microbial synthesis has allowed to produce nanoparticles that are biocompatible, stable, and safe. Microorganisms allow crystal growth and prevent aggregation. Microorganisms act as reducing and capping agents because microorganisms provide enzymes, peptides, poly(amino acids), polyhydroxyalkanoate, and polysaccharides. Here, we review microorganisms-based synthesis of nanoparticles containing gold, silver, platinum, palladium, copper, titanium dioxide, zinc oxide, iron oxide, and selenium. The size of nanoparticles ranges generally from 1 to 100 nm with spherical, rod shape, triangular, cube, and hexagonal shapes. We present nanoparticle properties and applications in waste treatment, cancer treatment, antibacterial, antimicrobial, antifungal, and antioxidants.

已使用自然资源在绿色条件下进行纳米粒子合成，以减少有毒化学品的使用。例如，微生物合成允许生产具有生物相容性、稳定和安全的纳米颗粒。微生物允许晶体生长并防止聚集。微生物充当还原剂和封端剂，因为微生物提供酶、肽、聚（氨基酸）、聚羟基链烷酸酯和多糖。在这里，我们回顾了基于微生物的含有金、银、铂、钯、铜、二氧化钛、氧化锌、氧化铁和硒的纳米粒子的合成。纳米颗粒的尺寸范围一般为 1 至 100 nm，具有球形、棒状、三角形、立方体和六边形。我们介绍了纳米粒子在废物处理、癌症治疗、
