Separation of micro- and nano-sized particles depending on electrophoretic mobility.
(a) Diameters: 4.8 and 9.9 μm, electrophoretic mobilities: −4.35 × 10−4 and −6.18 × 10−4 cm2·V−1·s−1 (trajectories of each particle; flow rate of Inlet 1: 1.0 μL/min; flow rate of Inlet 2: 50 nL/min; applied voltage: 66 V; membrane thickness: 1.3 μm). (b) Diameters: 100 and 500 nm; electrophoretic mobilities: −4.76 × 10−4 and −7.25 × 10−4 cm2·V−1·s−1 (snap shot with high contrast to distinguish particles; flow rate of Inlet 1: 0.5 μL/min; flow rate of Inlet 2: 30 nL/min; applied voltage: 63 V; membrane thickness: 5 μm).
