Simulation of flow characteristics in the microfluidic channel of the μPAC device. (a) Brightfield microscopic image of the PDMS micropost array embedded at the bottom of the microfluidic channel of the μPAC device. The inset shows the repeating geometrical unit used for flow simulation. Scale bar, 6 µm. (b) Simulation results of flow velocity (blue arrows) and streamlines (red curves) around the PDMS microposts. (c) Colorimetric maps showing magnitudes of the shear stress at different horizontal planes along the height of the PDMS microposts as indicated.
