| Abstract | ||||
| SYNTHESIS, characterization and comparison the anti bacterial activity of both silver/ polyvinyl alcohol (Ag/ PVA) nanocomposite and nisin, for some pathogenic bacteria was carried out. Applications of the nicin include dental care products, pharmaceutical products such as stomach ulcers and colon infection treatment and potential birth control. Ag/ PVA nanocomposite was prepared by in situ reduction method in which silver nitrate, gamma irradiation and PVA act as precursor, reductant and stabilizer respectively. The synthesized nanocomposites have potential antibacterial activity toward both Gram-positive and Gram-negative bacteria. Further studies have demonstrated the structure and the distribution of Ag nanoparticles caped within PVA polymer chain such as X-ray diffraction (XRD), transmission electron microscopy (TEM) were carried out. | ||||
