Analysis of conductivity and electric field distribution. (a) The simulated conductivity distribution in the first and second electrode regions. The conductivity of the modified DEP buffer is 14 mS/m, and the conductivity of the original DEP buffer is 1 mS/m. (b) The simulated electric field in the first and second electrode regions. The modified DEP buffer is introduced into I1 and the original DEP buffer is introduced into I2, when 88 V is applied on the device. (c) The distribution of Rhodamine B at the first and second electrodes regions without electric field. Scale bar: 100 μm. The velocity at the beginning of the main channel was set as 6 mm/s. The flow rate of the modified DEP buffer with Rhodamine B (10 μg/mL): 50 μL/hr, the flow rate of the original DEP buffer: 250 μL/hr.
