Bactericidal mechanisms and effector targets of TiO 2 and Ag-TiO 2 against Staphylococcus aureus

Bactericidal mechanisms and effector targets of TiO2 and Ag-TiO2 against Staphylococcus aureus

PURPOSE In our previous study, Ag+-loaded TiO2 and Ag+-loaded SiO2 coatings for tracheal intubation were prepared to prevent ventilator-associated pneumonia (VAP), but the antimicrobial targets and the underlying mechanisms of TiO2 and Ag-TiO2 (Ag+) are still unclear. We attempted to elucidate the antimicrobial activity and potential mechanisms against Staphylococcus aureus. METHODOLOGY The s...

The bactericidal efficacy of a photocatalytic TiO(2) particle mixture with oxidizer against Staphylococcus aureus.

By proving the bactericidal effects of a low-concentration titanium dioxide (TiO(2)) particle mixture against Staphylococcus aureus, we hope to ultimately apply a mixture of this type as part of a clinical treatment regimen. A bacterial suspension of S. aureus 1 x 10(5) CFU/ml was added dropwise to a TiO(2) particle mixture (19 ppm TiO(2)) and irradiated by ultraviolet (UV) light. The colony-fo...

The interdependence of structural and electrical properties in 1 TiO 2 / TiO / Ti periodic multilayers

16 Multilayered structures with 14 to 50 nm periods composed of titanium and two different 17 titanium oxides, TiO and TiO2, were accurately produced by DC magnetron sputtering 18 using the reactive gas pulsing process (RGPP). Structure and composition of these 19 periodic TiO2/TiO/Ti stacks were investigated by X-ray diffraction (XRD) and 20 transmission electronic microscope (TEM) techniques....
