Figure 5. Different electrode design configurations in ICEK to generate MVs for particle focusing. (A) planar floating electrode placed at the bottom of the microchannel (Xiaoming Chen et al., 2017), (B) polarizable plates placed near the microchannel walls (Song et al., 2016), (C) asymmetric electrodes placed at the bottom of the microchannel (Ren et al., 2016), (D ) a floating electrode placed in the flow-focusing device (W. Liu et al., 2016).
