Figure 1
Schematic illustrations of trap electrode arrays and its cross-sectional view with numerical simulation results. The color bar shows the electric field intensity (in V/m) for an applied AC signal. (a) Distribution of the electric field magnitude (in V/m), based on an applied potential of 8 Vpp at 10 MHz, is shown for each trap electrode inside the fluidic channel with color-scale plot. The white arrows, normalized vectors, indicate the direction of the dielectrophoretic force. The intensity of the applied electric field is maximal in close proximity to the edge of each ring-shaped electrode and is reduced to its minimum value at the center of the trap zone. (b) Motion trajectories of neurons with a radius of 5 µm under the distribution of applied electric field magnitude (in V/m). Numerals I-IV correspond to time: (I) Initial distribution of neurons in the domain, (II) position of the neurons after 0.3 s, (III) 1 s, and (IV) 2 s.
