Biosynthesis of AgNPs by using Brassica Oleracea Capitata and Inhibitory Effect on some Pathogens Bacteria

The use of plants as a source for the biosynthesis of nanoparticles is a recent development in nanotechnology because it is safe, easy and available. In this study, silver nanoparticles AgNPs were synthesis from Oleracea Capitata extract through mix 10ml of extract plant with 90ml (1mM) of the silver nitrate (AgNO3) after incubation at room temperature for 12h a color mixture change to dark brown, then the results characterization of AgNPs determined shown that the ranged peak 419 nm by using UV- visible spectroscopy, the results showed AgNPs spherical shape and their size ranged from 27.2 to 33 nm by using transmission electron microscopy (TEM), also FTIR determine presence of the functional groups of silver nanoparticles from rang 597.93 to 2972.31, the Ag-NPs inhibitory effect determined against Streptococcus pneumonia 14mm,Salmonella typhi18mm by used well diffusion method.
