FIG. 3.

Capture probability of Capan-1 cells, 3(a), PANC-1 cells, 3(b), BxPC-3 cells, 3(c), and PBMCs, 3(d), at the central axis of the Hele-Shaw DEP device as a function of shear stress under experimental conditions of no DEP (black bars), 50 kHz (light gray bars), and 200 kHz (dark gray bars). Bars represent the mean capture of the indicated number of experimental replicates (n), and error bars represent standard deviation. A Wilcoxon rank-sum test was used to compare between each pair of DEP conditions, and asterisks (*) indicate significance of differences (P < 0.05).
