Fig. 1 Schematic explanation for the methodology used to mycosynthesize NPs
this approach, the venomous metal ions are reduced to non-venomous metallic static
NPs as a catalytic impact of the metabolites and enzyme of the cell fungus (Salem
and Fouda 2020; Zhao et al. 2018). The mechanism involves, for example, reduction
of Ag
+ and Ag
0 via intracellular redox potential, and enzymes and/or proteins which
is secreted by the fungal cell (Rahman et al. 2019). These reactions may occur either
intracellularly or extracellularly (Fig. 2). For the extracellular mycosynthesis of NPs,
a number of mechanisms have been proposed. Ahmad et al. (2003) for the first time
proposed mechanism involved for the Ag-NPs mycosynthesis by F. oxysporum. The
