Abstract :Nanotechnology has opened new opportunities in the field of medical sciences and pharmaceuticals. Commercially, nanoparticles are in great demand in electronics, catalysis, chemistry, energy, and medicine. Today in nanoparticle production green synthesis, using biological material including medicinal plants as a starting material, is in vogue. In the present investigation the powder extract insert ignore into journalissuearticles values(stems and leaves); of an important medicinal plant, Verbesina encelioides, was used for the biosynthesis of bionanoparticles. The synthesized nanoparticles were screened and characterized by UV-visible spectrophotometer, scanning electron microscopy, X-ray diffraction, and FTIR analyses. The particles were then subjected to antimicrobial assay. Comparative analyses of the antimicrobial behavior of aqueous, ethanolic, and methanolic extracts and bionanoparticles against 2 bacteria insert ignore into journalissuearticles values(Escherichia coli and Vibrio cholerae); and 2 fungi insert ignore into journalissuearticles values(Aspergillus niger and A. flavus); are described.
Keywords : Key words Nanoparticles, green synthesis, UV visible spectrophotometer, scanning electron microscopy, X ray diffraction, FTIR, antimicrobial assay
