The high phenolic content of the hot water extract of C. officinalis
possesses strong anti-oxidant properties, that helped in the reduction
of Ag cations to Ag/NPs. The particles were synthesized using
C. officinalis and were characterized using various analytical techniques
such as XRD, TEM and FT-IR. UV–vis showed peaks at a wavelength of
430 nm, which established the formation of spherical nanoparticles. Finally,
we study the effect of some important parameter for the synthesis
