Green Synthesis of Copper Nanoparticles Using Ocimum Sanctum Leaf Extract

Abstract

Development of green nanotechnology is generating interest of researchers toward ecofriendly biosynthesis of nanoparticles. In this study, biosynthesis of stable copper nanoparticles were done using Ocimum sanctum leaf extract.  First we prepared leaf extract of Ocimum sanctum in deionised water. This extract added to 1mMol of copper sulfate solution and we observed the change in color of the solution from colorless to colored solution, this indicates that there is a formation of Cu nanoparticles.  These biosynthesized  Cu nanoparticles were characterized with the help of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR). It was observed that the Ocimum sanctum leaf extract can reduce copper ions into copper nanoparticles within 8 to 10 min of reaction time. Thus, this method can be used for rapid and ecofriendly biosynthesis of stable copper nanoparticles.
