Cyclic Strain Enhances Cellular Uptake of Nanoparticles

Figure 4

Phase contrast and fluorescence images of BAECs after nanoparticles uptake for 1 h (scale bar: 10 μm). The nucleus in each cell was labeled with DAPI staining (blue color). (a-b) Representing uptake of 100 nm nanoparticles by BAECs with 15% stretching for 1 h. (c-d) Representing uptake of 100 nm NPs by BAECs incubated for 1 h without stretching. Nanoparticles (green color) are seen outside of the nucleus. (e-f) Control experiment without nanoparticle incubation.
