A short review on biosynthesis of cobalt metal nanoparticles

Nanotechnology is study of nanoscale material properties dependent on their size, shape, and morphology. The establishment of this area will have a numerous advantage towards world industry and technology because it can be utilized globally for various application such as healthcare, electronic, cosmetics, chemical, energy and composites. Along with the time, various of synthesis method such as chemical and physical methods emerging. Somehow these method starts to show its limitations. Thus, the requirement to find another alternative way to synthesis nanoparticles that are not going to cause environmental hazards are urgently needed. A development of eco-friendly approach for synthesis of nanoparticles mainly are desirable in order to move forwards towards green chemistry. At present, plants have shown to be proven and efficiently applied for the extraction method for cobalt oxide nanoparticles. Therefore, this short review includes methodologies and benefit as well as recent studies to produce cobalt oxide nanoparticles using green synthesis. (C) 2019 Elsevier Ltd. All rights reserved.
