TiO(2)prolatenanospheroids (PNSs) may be photosensitizers (PSs), which act by catalyzation of hydroxyl radical ((OH)-O-center dot) formation upon light illumination.(OH)-O-center dot might, in turn, contribute to killing of cancer cells. On the other hand, there is great concern about toxicity in the dark of TiO(2)nanoparticles in general. In this work, we have investigated the biocompatibility of TiO(2)PNSs of the anatase crystal form (length between 100 and 300 nm and width 50 nm) in the dark with immune cells and light-induced cytotoxicity on several cancer cell lines. The effects of the treatment of different cell lines with several concentrations of TiO(2)PNSs suspensions showed the specifics of cells' viability and the intracellular localization. The results of in vitro studies obtained by cytotoxicity assays adjusted to individual cell lines' metabolism point towards the biocompatibility of TiO(2)PNSs at low and moderate concentrations in the dark, which neither kill the cells, nor induce activation of the immune system cells. Laser scanning confocal microscopy revealed that PNSs are taken up by cells, and insight into the intracellular distribution was obtained in this study.
