the green methods are one of the easy, fast, cheap and environmentally safe ways, which is done using plant to extracts of Nanoparticles. This review deals with the latest studies on the green method of metallic nanoparticles using plant extracts. the different plant parts (roots, stems, leaves, fruits, peels, seeds) to be extracted for the production of nanoparticles of many metals, the most important of which are silver (Ag), gold (Au) and oxides of some metals such as zinc oxide (ZnO), copper oxide (CuO), iron oxide (Fe3O4) and other metal oxides. The study also addresses some examples of the use of metallic nanomaterials as anti-bacterial and anti-fungal.
