Dielectrophoretic force as a function of frequency from 300 to 700 kHz of 0.00 mM (native) (a), 0.07 mM (b), 0.11 mM (c), and 0.17 mM (d) Triton X-100 treated RBCs. DEP force profiles were calculated from cell velocities and represented via a box-and-whisker-inspired representation whereby the colored regions show the interquartile ranges, while the min and max lines for the whiskers show the full force range (patterned area) for all cells in the test region. The median force is the boundary between yellow and gray.
