Green synthesis of nanosilver particles from extract of Dracocephalum Lindbergii

Abstract

We describe the synthesis of silver nanoparticles (Ag-NPs) using aqueous extract of Dracocephalum lindbergii . UV–visible spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray energy dispersive spectrophotometer (EDX) were performed to ascertain the formation of Ag-NPs. UV-visible absorption spectra of the reaction medium containing silver nanoparticles showed maximum absorbance at 416 nm. The XRD pattern revealed the crystalline structure of SNPs. The SEM analysis showed the size and shape of the nanoparticles. The environmental friendly method provides simple, easy and cost effective faster synthesis of nanoparticles than chemical methods and can be used in several areas such as food, medicine.
