Figure 6

Electron micrographs of the interaction between particles and the apical plasma membrane of A549 cells. A: Exposure to 1 μm particles (P). Three particles in the process of cellular uptake, probably via macropinocytosis or phagocytosis. Scale bar = 1 μm. B: Exposure to 0.05 μm particles (P). One particle in the process of cellular uptake, probably via clathrin- or caveolae-mediated endocytosis. Scale bar = 500 nm.
