An Introduction to Microbial Metal Nanoparticle Preparation Method
Reduction of metal is an important defense mechanism in microorganisms as a way to manage metal toxicity. The inherent, clean, nontoxic and environmentally friendly ability of eukaryotic and prokaryotic microorganisms to form the metal nanoparticles is particularly important in the development of nanobiotechnology. New methods have been developed to control disparity, chemical composition, the size, and the shape to get the best particles which can be well applied in different fields of science. However, there is a growing need to understand the basics of this technique to facilitate application of the new methodology to laboratory and industrial needs. This review contains a brief outlook of the processes and classification of metal nanoparticles biosynthesis by different microorganisms.
