Green synthesis of metal and metal oxide nanoparticles has been a highly attractive research area over the last decade. Numerous kinds of natural extracts i.e., biocomponents like plant, bacteria, fungi, yeast, and plant extract have been employed as efficient resources for the synthesis and/or fabrication of materials. Among them, plant extract has been proven to possess high efficiency as stabilizing and reducing agents for the synthesis of controlled materials (i.e., controlled shapes, sizes, structures, and other specific features). Studies have expanded the self-assembly of nanomaterials, particularly in the fast developing field of building large-scale and long-range ordered structures from multi-component and multidimensional nanomaterials. Here we synthesized metal and metal oxide nanoparticles from plant extracts and characterized using uv visble spectroscopy and scanning electron microscopy.
