To synthesise the silver nanoparticles using the extracts of Basella rubra Linn and to investigate the antibacterial activity against human pathogens and invitro cytotoxic activity o human breast cancer cell line (MCF-7).In the present study silver nanoparticles were synthesized using the methanolic extract of Basella rubra and were characterized using UV-Visible spectroscopy and SEM analysis. Further these synthesized silver nanoparticles were evaluated for their antibacterial activity against Escherichia coli, Pseudomonas aeroginosa, Staphylococcus aureus and Klebsiella pneumonia by disc diffusion method. The silver nanoparticles were assessed for its cytotoxic activity on human breast cancer cell line (MCF-7).SEM showed the formation of silver nanoparticles with an average size of 20-25nm.Biosynthesised silver nanoparticles showed potent antibactericidal activity against human pathogenic bacteria. The invitro screening of the biosynthesized silver nanoparticles showed potent cytotoxic activity against the human breast cancer cell line.
Keywords: Basella rubra, Silver nanoparticles, human pathogens
