Abstract
In modern days the study and research of metallic nanoparticles is one of the important fields of science due to its important application in the field of catalysis, bio-medical, sensors, antimicrobials, catalysis, agricultural field etc. The green synthesis of nanoparticles have proved to be better than the chemical method due to the large amount of capital involved in production in chemical method and it can solve the difficult environmental challenges like solar energy conservation , agricultural production, catalysis etc. These biocompatible nanoparticles exists in the form of mono-metallic nanoparticles or in two or more metals as alloys found extremely beneficial applications as antioxidant, anticancer, antimicrobial, antidiabetic, anticoagulant agents. In this review, an attempt is made to project the different routes of bio-synthesized processes to obtain metallic nanoparticles and their biomedical utilizations.
