The influence of particle concentration on survival rates of cells. TiO2 particles in various concentrations were added into culture plated with confluent cells. After incubation for 24 hours, the cell viability was then quantified with Live/Dead cytotoxicity Viability stain (Molecular Probes). The cell viabilities were then normalized with cells without treatment. Vertical lines denote ± 1SD (n=4 for all test samples and cells). Significant of differences between cancer cells vs. 3T3 cells (▲): **, P<0.05).
