Green Synthesisof Silver Nanoparticles Using the Extraction of some Plants Leaves

Abstract

We have applied a green method for preparing silver nanoparticles (Ag NPs) using the extractof Ficus carica and SolanumIncanumLeaves. These extraction of plants leaves keptin an aqueous solution and used as a reducing agent and surfactant in the reaction. The structure and size of Ag nanoparticles are studied usingXRD spectrums while anoptical properties studied byUV-VISB spectrophotometer. The results showed that,the average grain size is in the range of 15-21nm usingDebye- Scherer equation and 25-27nm using Hall-Williamson equation.In addition,we applied this study to investigate the antimicrobial activity of Ag NPs synthesized using Ficuscarica L (FCL) extract.The obtained results are compared for both positive gram Escherichia coli (E. coli) and negative gram Staphylococcus aureus (S. aureus) bacteria.Finally, we have compared the antimicrobial activity of Silver nanoparticles with some antibiotic.
