Nanobiotechnology, bionanotechnology, and nanobiology are terms that have emerged in reference to the combination of nanotechnology and biology. Through the convergence of these disciplines, the production of metallic nanoparticles (NPs) using biological material as reducing agents is rapidly progressing. In the near future, the application of clean, non-toxic, and eco-friendly nanostructured material will be possible in industry and/or biomedicine. Currently, there is a wide range of organisms that have been reported to be useful in producing NPs. However, the development of finer protocols and the applicability of biosynthesized nanostructures are presently under study. Silver and gold are among the most studied metals due to their potential use in medical treatment. In fact, silver NPs have been evaluated as antimicrobial agents, having been successfully used against several types of fungi and bacteria. However, the use of such material in our daily life must be carefully evaluated. This article summarizes some of the most significant results using organisms to produce metallic NPs as well as the microscopic analyses used to characterize the nanostructured material obtained, providing a valuable database for future research.
纳米生物技术、生物纳米技术和纳米生物学是指纳米技术与生物学的结合。通过这些学科的融合，使用生物材料作为还原剂来生产金属纳米粒子（NPs）的技术正在迅速发展。在不久的将来，清洁、无毒和环保的纳米结构材料将有可能在工业和/或生物医学领域得到应用。目前，已经有很多种生物体被报道可以用于生产 NPs。然而，目前正在研究更精细的方案和生物合成结构的适用性。银和金是研究最多的金属之一，因为它们有可能用于医疗。事实上，银 NPs 已被评估为抗菌剂，已成功用于对抗几种类型的真菌和细菌。然而，这种材料在日常生活中的使用必须仔细评估。本文总结了一些使用生物体生产金属 NPs 的最重要的结果，以及用于对所获得的纳米结构材料进行微观分析的方法，为未来的研究提供了有价值的数据库。
