Synthesis of silver nanoparticles was extensively studied
employing chemical and physical methods, but the development
of reliable technology to produce nanoparticles is an
important aspect of nanotechnology (Natarajan et al., 2010).
Synthesis of nanoparticles by physical and chemical methods
may have considerable environmental defect, technically
laborious and economically expensive (Gopinath et al., 2012).
The biological methods, using microorganisms and enzymes,
have been suggested as possible eco-friendly alternatives
(Mohanpuria, Rana, & Yadav, 2008).
