Abstract

 The current study (in Khalkhal, 2014) deals with a simple nano phytosynthesis approach to produce silver nanoparticles (AgNPs) using a methanolic extract of the leaves of CHRYSANTHEMUM PARTHENIUM along with evaluation of the corresponding physicochemical properties. Accordingly, AgNPs were analyzed and characterized by UV/Vis SPECTROPHOTOMETRY and FT-IR spectroscopy. In addition, the morphology and size of the reduced silver nanoparticles were deter-mined by the transmission electron microscope (TEM), scanning electron microscope (SEM) and X-ray diffractometer (XRD) instrumentations. The FT-IR spectra of plant methanolic extract taken before and after synthesis of nanoparticles, showed the possible functional groups for the formation of AgNPs. Moreover, the SEM accounted for the formation of AgNPs with a mean size of 43.1 nm. The TEM study also confirmed the formation of AgNPs over the average size of 30-50 nm. Finally, the XRD pattern showed that the silver nanoparticles are crystalline in nature with a face-centered cubic (FCC) structure and a mean size of 46.7 nm. The suggested approach involving NANOPHYTOSYNTHESIS of AgNPs using the leaves of C. parthenium serves as a beneficial, effective, rapid, eco-friendly and easy alternative to conventional synthetic methods.
