Paper Title
Synthesis and Characterization of Green Silver Nanoparticles

Abstract
A novel, non-toxic, eco-friendly biological material; Bellevalia flexuosa Boiss (Asparagaceae) was used to biosynthesize silver nanoparticles(AgNPs). The plant was milled and soaked in Chloroform. The resulted solvent was reconstituted in methanolic mixtures and evaporated several times to yield the dried methanolic extract. Silver nanoparticles were prepared and studied by changing the reaction conditions with respect to the concentrationsof silver nitrate (AgNO3), Bellevalia extract and Ammonia solutions, pH and temperature. The green nanoparticleswere studied using UV–visible spectra and zeta sizer. The zeta sizer was used to determine the mean particle size, polydispersity index and zeta potential of the nanoparticles and to study their stability. In addition, X-ray diffraction analysis (XRD) and Infra-red spectroscopy (FTIR) were used to characterize the nanoparticles. The morphologies of AgNPs were investigated using (SEM). Energy Dispersive X-Ray Analysis (EDAX) was used to identify the elemental composition of AgNPs. Finally, the antimicrobial activity of the formed AgNPs was displayed. In conclusion, AgNPs can be produced using economic and eco-friendly method for their antimicrobial applications.
