Název v původním jazyce

The Study of TiO2 Thin Films Photocatalytic Degradation of Yeast and Dye Pollutants

Popis výsledku v původním jazyce

The antimicrobial properties of TiO2 thin films were tested on photocatalytic killing of yeasts Candida tropicalis and Candida albicans. Generally, Candida is the most common cause of opportunistic mycoses (Candidiasis) worldwide. The antimicrobial effect of photocatalysis with TiO2 could be due to the presence of reactive oxygen species (ROS), such as superoxide (O2o-), hydrogen peroxide (H2O2), and hydroxyl radical (HOo), generated either by illuminated TiO2 or by the illumination (mainly UV) of the cells. TiO2 layers were immobilised by dip-coating method on soda-lime glass plates using sol-gel method with titanium tetraisopropoxide precursor in ethanol. The dependence of Candida tropicalis and Candida albicans survival ratio on irradiation time wasdetermined by epifluorescent microscopy using Acridine Orange dye. The influence of TiO2 layer number on the photocatalytic oxidation 2,6-dichloindophenol was also studied in a desk reactor. The concentration decrease of 2,6-DCIP was eva
