Synthesizing plant-derived nanoparticles attract attention due to both their broad-spectrum biological applications and sustainable production. This paper describes the production of Cobalt oxide nanoparticles (Co3O4 NPs) using M. charantia leaf extract. The Uv–Vis absorption spectrum of them has peaks at 309 and 595nm. FTIR spectroscopy reveals bands at 580cm-1 and 667cm-1 and confirms the formation […]
