Green synthesis of silver nanoparticles using plant leaf extraction of Artocarpus heterophylus and Azadirachta indica

Abstract

It is well studied that the silver nanoparticles were strong candidate for antimicrobial activity and cancer therapy. To prepared silver nanoparticles free from toxic chemical components, we prepared silver nanoparticles using biological method. The purpose of this work is to study the effect of two different plant’s leaf extract i.e., Artocarpus heterophylus and Azadirachta indica as a reducing and stabilizing agents on silver nanoparticles synthesis. The obtained silver nanoparticles are studied using X-ray diffraction spectrum to confirm its orientation and crystal structure. Shape, average size and crystalline nature are investigated and estimated using scanning electron microscope images and transmission electron microscopy with selected area diffraction pattern. The possible bio-reducing agents within the leaf extracts are confirmed using FTIR analysis. This study provide a chemical free synthesis method to produce silver nanoparticles and provide a better approach to produce the nanoparticles which can be used for medical as well as cosmetic purpose.
