Poisonous weed leaf extract mediated biosynthesis of silver nanoparticles and evaluation of their antibacterial activity
Abstract
Silver nanoparticles were synthesized by using leaf extract of a poisonous weed Ipomoea carnea Jacq. Leaf extract reduces silver ions to silver nanoparticles. Synthesized nanoparticles were confirmed by UV-Visible spectrophotometer and UV-Visible absorption spectra of the reaction mixture showed λ max at 475 nm. The average particles size was confirmed by XRD peaks was 20 nm. SEM image showed aggregates of spherical silver nanoparticles. Antibacterial efficiency of silver nanoparticles was evaluated by disc diffusion assay method. Silver nanoparticles exhibited antibacterial activity against Staphylococcus aureus NCIM-2079 and Pseudomonas aeruginosa NCIM 2200. This cost-effective, eco-friendly and easily scald up biosynthesis method of silver nanoparticles synthesis using leaf extract of a poisonous weed Ipomoea cornea Jacq. will be compatible for pharmaceutical and medical applications.Downloads
