Schematic of the working principle of streaming dielectrophoresis (DEP). Cells can be focused into streams of specific width T and separation G between each other. Retrieval geometries can be used for continuous extraction from the channel. The impact of device geometry and experimental parameters on the composition and width of the streams is studied here. Specifically, we study the impact of electrode shape (circles, diamonds, lens-shaped) and height (10%, 50% and 100% of the channel height) as well as flow rate and cell concentration in the sample.
