Metal nanostructures have unusual physicochemical properties and biological activities compared to their bulk parent materials. Thus in recent years a number of physical, chemical and biological techniques were applied for the development of metal nanoparticles (NP). Here we have synthesized silver and gold nanoparticles (AgNPs and AuNPs) by using leaves extracts of Rosa rugosa. Surface plasmon resonance spectra for silver and gold are obtained at 451 and 578 nm with brown yellow and pink-red color, respectively. AgNPs and AuNPs vary in size according to different leaves extract and metal concentration used for the synthesis. Different instrumental techniques were applied to characterize the synthesized AgNPs and AuNPs viz. UV-vis, TEM, XRD, FTIR, Zetasizer and EDX. The synthesized NPs were mostly spherical (in case of AgNPs) with some triangular and hexagonal (especially in case of AuNPs) in shapes with an average size of 12 and 11 nm for AgNPs and AuNPs, respectively.
