Abstract
Today, nanotechnology is widely used in science and technology are growing rapidly. Nanoparticles synthesized with the help of plant extracts, due to the lack of use of external chemical agents, can have fewer side effects in medical applications.In this article, we synthesize silver nanoparticles (AgNPs) using the aqueous extract of Stachys lavandulifolia vahl. Plant extract in the synthesis of nanoparticles acts as a reducing and stabilizing agent and can also have fewer side effects in medical use and is environmentally friendly. The average size of nanosilver synthesized by this method is 68-69 nm and factors such as temperature, concentration, pH and time were investigated to optimize the reaction. Formation of silver nanoparticles was confirmed by UV–Vis spectroscopy, Energy Dispersive Spectroscopy (EDS) analysis , X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM)
