ECO-FRIENDLY PHYTO-SYNTHESIS OF SILVER NANOPARTICLES USING COLCHICUM AUTUMNALE AND ITS CHARACTERIZATION.

Metal nanoparticles have been produced chemically and physically for a long time; however, their biological production has only been investigated very recently. Plant mediated synthesis of nanoparticles is a green chemistry approach that interconnects nanotechnology and plant biotechnology. In the present study, we report biogenic fabrication of silver nanoparticles by a simple procedure using leaf broth of Colchicum autumnale without extra surfactant, capping agent, and/or template at ambient conditions. The AgNPs were characterized by UV-visible spectrophotometer, X-ray diffraction (XRD), particle size analyzer (DLS), scanning electron microscopy (SEM). The size of synthesized nanoparticles are in the range of 70-250nm which was confirmed by DLS and SEM micrographs. The size of nanoparticles decrease with increase in broth concentration. Morphology of the silver nanoparticles wasspherical and its distribution, monodisperse. AgNPs are crystallized in face centered cubic symmetry.
