There is a growing interest in biosynthesis of nanoparticles using methods that are simple, inexpensive,  and non-toxic to the environment. Among the different available methods of synthesis (including physical and chemical methods), the biological methods are considered to be the most convenient in terms of cost and non-hazardous impacts to the environment. Nanoparticles are proven to possess unique chemical and physical properties with respect to their bulk material equivalents, which enhance their effects when used in similar applications.  Such enhancements are related to their larger surface-area to volume ratio. Although many biological systems have been reported for the synthesis of  metallic nanoparticles (NPs), the actual mechanism of myco-synthesis of nanoparticles is still not fully understood. Biosynthesis of NPs is suggested to be a complicated process in which various biomolecules are involved as reducing and/or capping agents

In this research, a main target was to investigate the mechanism of AgNP synthesis using filtrate of Fusarium solani MH005062.
