Green Synthesis and Morphological Investigation of Silver Nanoparticles Using Greater Burdock (Arctium Lappa) Aqueous Extracts

Silver nanocomposite synthesis using Arctium Lappa is quite new in all respects hence it can be investigated as an innovation. Moreover, it, as a green technique, is also enumerated amongst the novel researches in Iran and the world. The present study has been conducted for silver nanocomposite synthesis as a green and highly safe method. The method not only leads to the production of a large amount of nanoparticles free of any pollution but also the produced nanoparticles are very appropriate in terms of morphology. In a biological process where the Artium Lappa fruit's aqueous extract was applied as a capping and reducing agent, nanoparticles (NPs) of silver were synthesized. These Silver NPs were classified via X-ray diffraction (XRD), Fourier transformed infrared spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and UV-visible spectroscopy. According to the obtained results, it can be stated that arctium lappa is capable of silver nanoparticle synthesis and it was also observed in SEM spectrum that silver nanoparticle are in a range between 20nm and 30nm in size indicating the suitability of arctium lappa for synthesizing silver nanoparticles in desirable dimensions.
