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 tenuiflorum leaf extract. First we prepared leaf extract of Ocimum tenuiflorum in deionised water. This extract added to 1mMole of copper sulfate,silver nitrate 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,siver nanoparticles were characterized with the help of Fourier transform infrared spectroscopy (FTIR).ultraviolet spectroscopy (UV) It was observed that the Ocimum sanctum leaf extract can reduce copper ions,and siver ions into copper,andsiver nanoparticles within 8 to 10 min of reaction time. Thus, this method can be used for rapid and ecofriendly biosynthesis of stable copper.siver nanoparticles.
