Description :
Green synthesis of nanoparticle is a novel way to synthesis nanoparticles by using biological sources. It is gaining attention due to its cost effective, ecofriendly and large scale production possibilities. In this present study six plants Hibiscus rosa sinensis, Moringa oleifera, Azadirachta indica, musa balbisiana, ocimum tenuiflorum, and Punica granatum were taken to investigate their potential for synthesizing silver nanoparticle. The silver nanoparticles synthesized were confirmed by their change of color to dark brown due to the phenomenon of surface plasmon resonance. The characterization studied was done by UV-VIS spectroscopy. All the six plants synthesized silver nanoparticles show good antimicrobial activity against clinically important pathogens Pseudomonas aeruginosa, Klebsiella pneumoniae, Bacillus subtilis, Staphylococcus aureus and Escherichia coli. The studies describing the biosynthesis of silver nanoparticles followed by the investigation of antimicrobial and scavenging activities may be useful for green nanotechnology research opening a new area in this field.
