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 of silver nanoparticles such as temperature, pH, formation time,
concentration of silver nitrate solution and wt.% of seed extract for the
proposed method.
