DEP spectra. (a) HCT116 DEP spectra for solutions of three different conductivities across the frequency range of 0.1 MHz to 100 MHz, and HCT-116 spectra with dyed (Hoechst 33342) samples at 0.1X PBS. In both cases (without and with dye), they have their first cross-over frequency at virtually the same value. (b) MCF-7 DEP spectra for solutions of three different conductivities across the frequency range of 0.1 MHz to 100 MHz. The dashed line intersects at 3.2 MHz, where the cell separation was most efficient.
