Cell toxicity of functionalized particles. (A) LDH release from LLC cells following TiO2 exposure. Cells with 70–90% confluence were exposed TiO2 particles for 3 hours. The LDH activities of supernatants and adherent cell lysates were then determined spectrophotometrically. (B) MTT assay on particle-exposed LLC cells. LLC cells were incubated with variously functionalized TiO2 particles for 3 hours. The activity of adherent cells was then quantified with MTT assay kit. The viable cells were then determined spectrophotometrically. The vertical lines denote ± 1SD. Significant of differences between particle incubated cells vs. untreated cells: **, P<0.01).
