Recently, biosynthesis of nanoparticles has attracted scientist’s attention because of the use of environmentally friendly nanoparticles that do not produce toxic wastes in their process of synthesis. In this study we investigated the biosynthesis of silver nanoparticles using three fungi: Aspergillus niger, Fusarium oxysporum and Alternaria solani. These silver nanoparticles were characterized by means of UV-vis spectroscopy, scanning electron microscope (SEM). Results indicate the synthesis of silver nanoparticles in the reaction mixture. The synthesis of nanoparticles would be suitable for developing a microbial nanotechnology biosynthesis process for mass scale production.
