Abstract:
The present study involves the green and eco-friendly synthesis of CuNPs using the leaves extracts of the plant Costus pictus. For CuNPs synthesis the different bio-components present in the leaves extract works as a reducing agents. The synthesized CuNPs were characterized by UV-visible spectroscopy, Scanning Electron Microscopy (SEM), EDAX and FTIR. The CuNPs formed were confirmed by the characteristics surface plasmon resonance (SPR) peak found at 560nm 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. These CuNPs were investigated for potential use as an antimicrobial agent to inhibit pathogenic bacteria and fungi. Their antibacterial activity was tested on Escherichia coli and Staphylococcus aureus and the antifungal activity was tested on Aspergillus niger and Candida albicans. The results showed that CuNPs had a high antimicrobial activity.
