Abstract

In this research, silver nanoparticles were successfully synthesized using green approaches. Biosynthesis using plant extract was applied as a green method to the preparation of silver nanoparticles. In this work, the effect of Wheatgrass extract was investigated as reducing an agent. As-synthesized silver nanoparticles were characterized using several physical methods such as, powder X-ray diffraction (XRD), Transmission electron microscopy (TEM), FT-IR analysis, UV-vis spectroscopy and dynamic light scattering method (DLS). The result of TEM images showed that silver nanoparticles were formed as spherical particles with high monodispersity and size 21-32 nm. Additionally, the size distribution of these nanoparticles was calculated with DLS histogram which the result was in agreement with the result of TEM image with average size 28 nm. Since, the Wheatgrass extract play an important role as the capping agent, the present of this extract on the surface of silver nanoparticles was to study using FTIR analysis and the result approved the present of many functional groups on the surface of nanoparticles. Briefly, this strategy provides a simple, cost effect and eco-friendly way to prepare nanoparticles without using hazardous chemical agents. © 2019, Dorma Journals. All rights reserved.
