GREEN SYNTHESIS AND CHARACTERIZATION OF COPPER NANOPARTICLES DERIVED FROM MURRAYA KOENIGII LEAVES EXTRACT

In recent years the green and eco-friendly method of synthesis for metal nanoparticles is an emerging field in nanotechnology and nanoscience. The importance of nanoparticles in society and industries is due to the remarkable change in the physical and chemical properties of the materials in the nano dimension. The Copper nanoparticles (CuNPs) are mostly found in their applications in the field of medical, electronic devices, biosensors, reagents in various reactions, lubricants, anti-biotic, anti-fungal, anti-microbial agents, and many more. The present study involves the green and eco-friendly synthesis of CuNPs using the leaves extracts of the plant MurrayaKoenigii (Curry leaves) and 1 mM Copper Sulphate (CuSO4 center dot 5H2O) solution. For this synthesis, the different bio-components present in the leaves extract works as a reducing agent. The synthesized CuNPs were characterized by UV-visible spectroscopy, Scanning Electron Microscopy (SEM and FTIR. The CuNPs formed were confirmed by the characteristics surface plasmon resonance (SPR) peak found at 340nm in UV-visible spectra. The morphological study from SEM images, it is confirmed that unsymmetrical spherical size Copper nanoparticles settled on leaves extract residue. FTIR spectrum clearly illustrates the green synthesis of copper nanoparticles mediated by the leaves extract. The method is fast and easy. As it does not involve the use of harmful and costly chemicals, it is more economical.
