ABSTRACT

Biosynthesis of nanopraticles has attracted scientist’s attention in recent times because of the necessity to develop new, clean, cost effective and efficient synthesis techniques. In particular, metal oxide nanopraticles are receiving greater attention since there is more scope for varied applications. In this study, we describe cost effective and environment friendly technique for biosynthesis of stable copper oxide nanoparticles has been obtained in Curcuma aeruginosa by using its powdered rhizome extract. This extract was added to the 3mMol of copper sulphate solution and the change in colour indicates the formation of copper oxides. These biosynthesized copper oxide nanoparticles were characterized with the help of Vis spectrophotometer (UV), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX). The CuO nanoparticles were found to exhibit antibacterial, antifungal and antioxidant activity.
