Abstract


The applications of nanoparticles are gaining a significant role in the current scenario as they show excellent anti-bacterial and antibacterial and antitumor activities. Biosynthetic methods of nanoparticles have emerged as a simple alternative to more complex chemical synthetic procedures to obtain nanomaterials. In the present scenario, algae are being used largely for the nanoparticles synthesis. In the present study, copper oxide nanoparticles (Cuo NPs) are biosynthesized by using Chlorella vulgaris, a marine alga. Further, the characterization, optimization and antimicrobial studies of the nanoparticles were carried out. The biosynthesized Cuo NPs were confirmed visually by the appearance of dark brown colour formation in the mixture added with copper acetate. The existence of nanoparticles was confirmed by UV visible spectroscopy at 540 nm. Biosynthesized nanoparticles were characterized by SEM, EDAX and XRD. Further, antimicrobial potential studies of synthesized Cuo NPs were carried out against selected bacteria and fungi.
