Fig. 5From: Exposure to TiO2 nanoparticles increases Staphylococcus aureus infection of HeLa cellsHeLa cells imaged with confocal microscopy after 24 h in culture: a Control; b cells exposed to 0.1 mg/ml anatase, and (c) 0.1 mg/ml rutile. The actin cytoskeleton of HeLa cells was visualized using the green-fluorescent Alexa Fluor® 488 phalloidin and the nucleus was stained with propidium iodide. d Average size of HeLa cells exposed to 0.1 mg/ml TiO2 NPs for 24 h and unexposed controlBack to article page
