ABSTRACT:
The recent progress in the area of science and technology is the emergence of nanotechnology, and that having its role in all disciplinary field. In the nanotechnology, green way of metal nanoparticles synthesis plays an essential role nowadays. The advantages of using plant extract in the metal nanoparticles synthesis is less toxic, economic, environmentally friendly. The involvement of metal nanoparticles in the management of various chronic non-communicable diseases leads to the cause for new field Nano medicine. The management for various serious diseases without any side effect is the ultimate aim of all researchers in the scientific field with the help of nanomaterials and nanostructures. Diabetes mellitus kills most of the population next to cancer worldwide, in India diabetes mellitus death rate is going to be expected in the first place by 2045 by WHO. Though various medicinal plants were used for the curative application of diabetes mellitus, the nanotechnology gives insights into the research field for the biomedical application of metal nanoparticles. The nanomedicine in the drug delivery system has emerged its outlook and its mechanism of action were predicted by the researchers at present. This review discusses the recent reports of various green synthesized metal nanoparticles, its characterization and its antidiabetic activities both by in vitro and in vivo approaches.
