Figure 6. Different electrode design configurations in ICEK to generate MVs for particle trapping. (A) a floating electrode array for trapping 500 nm particles (Ren et al., 2015), (B)multiple floating electrodes (Tao et al., 2016), (C) rotating electric field and central electrodes for trapping 5-20 µm polystyrene (PS) particles (Y. Wu et al., 2016), (D) polarizable plate located on the microchannel wall for enrichment of 50-1900 nm particles (Cunlu Zhao & Yang, 2018).
