Green Synthesis and Antibacterial Activity Studies of Silver Nanoparticles From the Aqueous Extracts of Wrightia Tinctoria  

Abstract

Silver nano particles synthesised from the leaves of Wrightia tinctoria were characterised by following instrumental analysis -UV Vis spectroscopy, Scanning Electron Microscopy, Energy dispersive X-ray spectroscopy, Atomic force microscopy and X-ray diffraction. The interaction of the silver nanoparticle to the microorganism was studied in Pseudomonas aeruginosa and Bacillus subtilis through agar diffusion method, minimum inhibitory concentration, swarming motility assay and protein leakage assay. The nanoparticles were found to be more effective against the bacteria used in this study.
