Fig 10 Particles influence on cell membrane integrity. (A) The disrupted cell membrane
of TiO2exposed LLC cells were stained with FM1-43 membrane stain (red). (B) TiO2
particles can be visualized surrounding cells under phase contrast optical microscope.
(C) By overlapping membrane stain images and optical image, membranes can be seen
to coincide with the particles indicating potential involvement of particles on cell
membrane disintegration.
