Figure 7

Intracellular particle number and surface area upon exposure to the same particle number. Cells were exposed to the same number concentration of particles (3 × 107 particles per well) and the number of intracellular particles was counted by LSM. From the number of intracellular particles, the total particle surface area taken up by the cells was calculated. There was a greater number (A) and surface (B) of 1 μm particles inside the cells than of 0.05 μm particles. Due to the small sample size (n = 3) and the use of the Mann Whitney u-test, these obvious differences failed to reach statistical significance (p = 0.1). Note the logarithmic scale on the y-axis in B.
