Green synthesis of nanoparticles as a simple, low-cost and eco-friendly method compared to the Physical and chemical methods and its materials have become more widely used. In the green synthesis of plants, algae and microorganisms and their components are used as reducing agents for the production of nanoparticles. In the meantime, biosynthesis Nanoparticles by microorganisms due to high environmental compatibility reduced energy consumption and cost taken into attention. Various microorganisms to carry out their vital processes from organic sources and minerals feed on the environment, these organisms are highly resistant to metals and when exposed to metal ions, they produce nanoparticles by different mechanisms. Metallic nanoparticles can be used for various fields such as optics due to their unique physical and chemical properties, catalysts, antimicrobials, medicine and food packaging. This paper describes how microorganisms can synthesize metal nanoparticles as well as their function and application in biomedicine. |
