Figure 3.

Electric field intensity map. The represented norm of the electric field is at the origin of the dielectrophoretic repulsion of RBCs away from the electrodes. As it can be seen, the higher gradient regions are located at the corners of the lateral electrode channels, as well as in front of them. Then the cell trajectory builds up as a combination of the hydrodynamic focusing against the electrodes and the dielectrophoretic repulsion towards the lower part of the channel occurring at each electrode pair.
