| Summary: | In this reaserch, photocatalyst titanium dioxide was doped with silver and modified by polyethylene glycol by sol gel method and the samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The purpose of the present study was to evaluate the photocatalytic bactericidal effects of prepared nanocomposite on human pathogenic bacteria under visible light irradiation whereas; many studies have been published on the use of titanium dioxide as a photocatalyst, which decomposes various organic compounds. We observed that TiO2 reveals the bactericidal property against the Staphylococcus aureus, Shigella dysanteriae, Salmonella enterica subsp. enterica serovar Paratyphi bacteria and pathogenic fungi Candidia albicans which is increased by the essence of silver and visible light. |
