Green bio-synthesis of Silver Nanoparticles Using Ziziphora tenuior L Water Extract

Document Type: Research Paper



Different biological methods are gaining recognition for the production of silver nanoparticles (Ag-NPs) due to their multiple applications. The use of plants in the synthesis of nanoparticles emerges as a cost effective and eco-friendly approach. In the present study, the synthesis of silver nanoparticles by using Ziziphora tenuior L of water extraction was carried out. For this purpose the water extract of Ziziphora tenuior L is used as the reducing agent. By addition of silver nitrate to this extract at room temperature, the color of the extract changed from pale yellow to dark brown, which showed the formation of silver nanoparticles. The characteristics of the obtained silver nanoparticles were studied using different methods, which including; ultraviolet-visible spectroscopy (UV-Vis), powder X-ray diffraction (XRD), scanning electron microscopy (SEM). Ziziphora tenuior L was found to display strong potential for the synthesis of silver nanoparticles by rapid reduction of silver ions (Ag+ to Ag°).
