FIG. 1.

A 2D schematic view of a circular particle electrophoretically migrating in a converging-diverging microchannel (a). The origin of the Cartesian coordinate system locates at the center of the throat where the cross section is minimal. Distribution and streamlines of the dimensionless electric field within a converging-diverging microchannel in the presence (b) and absence (c) of a particle. and shown in (b) represent the electrokinetic driving force and the negative DEP force exerting on the particle, respectively.

FIG. 2.

DEP choking regions in a constriction ratio vs particle size plane for different electric field intensities (a); in an electric field vs particle size plane for different zeta potential ratios (b); in a particle size vs zeta potential ratio plane for different electric field intensities (c); in an electric field vs zeta potential ratio plane for different particle sizes (d). Circles represent the actually numerical results used to draw these fitting curves as the boundaries between choking and nonchoking regions. The choking occurs in the region above each bounding curve.
