Figure 2A. Effects of the particle size on the cellular uptake of polystyrene nanoparticles in ECs. Values were obtained after one hour of incubation with nanoparticle solutions and represent mean ± SD (n=6). ** indicates significant differences compared to the 100-nm nanoparticle samples (p<0.001).

Figure 2B. Effect of concentration on the cellular uptake of 100-nm polystyrene nanoparticles in ECs. Values were obtained after one hour of incubation with nanoparticle solutions and represent mean ± SD (n=6).

Figure 2C. Effect of the incubation time on the cellular uptake of 100-nm polystyrene nanoparticles in ECs. Samples were incubated with 100 μ/ml of nanoparticle solution. Values represent mean ± SD (n=6).
