“…In the current scientific era, metal NPs have been commercially used in extensive areas including electronics, energy contact actions, and medicines. Optimization is the basic requirement as the conventional NPs synthesis methods are linked with toxic chemicals that are lethally harmful to the environment, as well as, living organisms which thereby retard the applicability of targeted material in biomedical field [ 6 , 7 ]. It is therefore desired to develop safe methods based on environment friendly process rather than associated with toxic chemicals [ 8 ].…”
