Bacteria and fungi as major bio-sources to fabricate silver nanoparticles with antibacterial activities.

Bacteriostatic and bactericidal effects of these nanoparticles can lead by production of reactive oxygen species and inactivation of biological macromolecules such as proteins and nucleic acids. The present review has tried to discuss recent progress and challenges about biosynthesis mechanisms and antibacterial activity of Ag nanoparticles bio-inspired by archaebacteria, actinomycetes, cyanobacteria, and fungi.
