From: Exposure to TiO2 nanoparticles increases Staphylococcus aureus infection of HeLa cells
Lactate dehydrogenase amount in HeLa control cells and cells exposed to 0.1Â mg/ml anatase, and 0.1Â mg/ml rutile TiO2. a Intracellular LDH; b Extracellular LDH. c Microrheology of HeLa cells exposed to TiO2. d Number of S. aureus bacteria per HeLa cell exposed to anatase, rutile and unexposed to TiO2 nanoparticles. TEM cross sections of HeLa control cells (e) and cells exposed to 0.1Â mg/ml anatase (f), and 0.1Â mg/ml rutile TiO2 (g) followed by exposure to S. aureus bacteria for 90Â min. Arrows point to bacteria. *Means PÂ <Â 0.05
