$TiO2 triggers biofilm formation by commensal bacteria: (A, B) the clustering effect of TiO2 on (A) E. coli and (B) E. faecalis in vitro was visualized by Nanolive imaging in the presence of 0, 0.5, 1, or 50 μg/ml TiO2 after 24 h incubation. False-coloring was applied to images based on refractive index, where black represents the refractive index of TiO2 and green represents bacteria.
