Nanoparticles are the most important entity in the widely spread field of nanotechnology. A series of numerous physical and chemical methods are involved in nanoparticle synthesis. Metallic nanoparticle can overcome the issues of highly monodispersed nanoparticles of various sizes, geometries and chemical composition, as they are comparatively smaller in size. Hence chemicals and non-polar solvents are involved in the synthesis of metallic nanoparticles which makes them unsuitable for being used in clinical fields. Therefore, the scientists have developed new aspects of clean, non-toxic, biocompatible and eco-friendly synthesis method for nanoparticles. Metal nanoparticles have attained a special focus attributed to their unique features like size and shape dependant optical, electrical and magnetic properties. The green synthesis using biological molecules obtained from plant sources are quite beneficial over other physical and chemical methods that have been used for metal nanoparticle synthesis and stabilization. This exhaustive review is focused on the metallic nanoparticles, which are synthesized from plant sources and overview of their pharmacological properties.
