Green synthesis of zinc oxide nanoparticles (Zno-Nps) Ailanthus excelsa Roxb. stem bark extract and its antibacterial activity

Abstract

Green nanoparticle synthesis from plant fruits aqueous extracts has been developed for a variety of applications.Zinc oxide nanoparticles by green synthesis method have recently piqued curiosity of researchers as well as scientists.Because of its in expensiveness, less harm to the ecosystem, non-toxicity, low cost and ability of act as acetrimide agent.Thus, the resent study reports synthesis of zinc oxide nanoparticles utilizing Ailanthus excelsa Roxb.stem bark methanolic extract.UV-visible absorption spectroscopy was used to evaluate a green chemistry produced zinc oxide nanoparticles.The antibacterial activity of synthesized ZnO-NPs against a bacterial strain of Staphylococcus aureus is demonstrated.It is observed that ZnO-NPs shows very potential antibacterial action by forming a zone of inhibition of 37 mm, it is a promising supplement which can replace hazardous chemical and physical antibacterial agents.
