“There is plenty of room at the Bottom”, a lecture of Richard
Feynman at the annual meeting of American Physical Society at the
California Institute of technology in the year 1959, was the beginning
of a new Science of Nanotechnology. Nanomaterials have a
long list of applicability in improving the human life and its environment
due to its optical and magnetic properties [1,2]. New and
novel strategies are a recent interest in the development of gold
and silver nanoparticles which have potential applications in
different fields like Biology, Chemistry, Medicine and material Science
[3e5]. Nanoparticles of very small size are essential for biological
labeling for SER Studies [6]. Presently, silver nanoparticles
have received greater attention due to their antimicrobial properties
[7]. The size, shape and structure of metal nanoparticles, can be
controlled and are very important to have strong correlation between
different optical, electrical and catalytic properties. There are
different physical and chemical methods available for synthesis of
nanoparticles which are not eco/environmentally friendly [8e12].
Priosynthesis of nanoparticles is now an emerging area of
nanoscience research by utilizing the rich source of plant, microorganisms
