Nanotechnology approaches to control diseases in
humans and plants have recently been increasing greatly,
and the unique physicochemical properties of
nanosized metal particles make it successful in biology
and medicine (Jo et al. 2009). Metal nanoparticles show
large surface to volume ratio and exhibit antimicrobial
properties due to their ability to interact with cellular
membranes (Ahmad et al. 2013). Silver has long been
known for its strong toxicity against a wide range of
microorganisms, including bacteria and fungi. Several
silver based compounds, including silver nanoparticles,
have been used as antimicrobial agents to kill or to
inhibit the growth or activity of human and plant pathogens
(Nomiya et al. 2004)
