Various approaches available for the synthesis of silver NPs include chemical, electrochemical [9], radiation , photochemical methods  and Langmuir-Blodgett

 and biological techniques. In this race of Ag NP preparation, plant-mediated green biomimetic synthesis of silver nanoparticle is considered a widely acceptable technology for rapid production of silver nanoparticles for successfully meeting the excessive need and current market demand and resulting in a reduction in the employment or generation of hazardous substances to human health and the environment. Studies have shown

that Alfalfa roots can absorb Ag (0) from agar medium and are able to transport it to the plant shoot in the same state of oxidation. Existing literature also reports successful synthesis of silver nanoparticles through a green route where the reducing and capping agent selected was the latex obtained from Jatropha curcas. Ag NPs were also obtained using Aloe vera , Acalypha indica , Garcinia mangostana leaf extracts

Thank U very much sir
