Eco-friendly synthesis of gold and silver nanoparticles from medicinal plants

Abstract

Present work is focused on the preparation of gold and silver nanoparticles using different plant material
in environmently friendly manner. There is no use of stabilizing agent or reducing agent, thus this method
could be categorized as green method and does not pose any harm to any living being. Nanoparticles are
synthesized and then characterized by UV-Vis Spectroscopy, IR and XRD analysis. The particle size of
different nanoparticles ranges from 13.5 nm to 31.5 nm. Further application of these nanoparticles could
be seen in their dye reducing activities in which Camelilia sinesis, Cladonia subtenuis, Pisum sativum,
Citrus aurantium and Punica granatumnanoparticles were used to reduce congo red dye.
