Internalization of Silver-nano-particles when treated on Allium cepa roots lead to DNA damage and different chromosomal aberrations. Also, Ag has been known for its antibacterial effect for a long time . In ancient Greece, Rome, and Macedonia, silver was used to control infections. Nowadays, silver is used for many bactericidal applications, for example, wound healing [3], water treatment [4], and flower preservation [5]. Other application fields of silver nanoparticles include catalysis [6], optics [7, 8], electronics [9], and various other areas of science and technology.
