left) Top view of the final spatial distribution of the Monte Carlo simulation (same of Figure 2) with superimposed the intensity map of $\left|{\mathbf{E}}_{\mathbf{rms}}\right|\left(\overrightarrow{\mathbf{r}}\right)$(same as Figure 2,right). The association between dipole chains and high regions of electric field is evident. Right) Top view of experimental spatial distribution of MDA-MB-231 after 180 sec of DEP manipulation. Black areas are associated to the metal electrodes. The chains are clearly present all around the electrodes.
