Towards fast plasma and blood cell separation - pattern and arrangement investigation of post arrays used in deterministic hydrodynamics

    Abstract

    We show that both the post pattern and arrangement have an influence on the cell movement (zigzag vs. bump mode) in deterministic hydrodynamics while the current theory is limited to one parameter, the array row shift ε for cylindrical posts. Besides, a new mechanism of cell movement, the “stair movement��? mechanism is reported; thereby, cells are laterally shifted across stream lines in a laminar flow. Our new designs greatly shorten the separation length (~1 mm vs. ~20 cm) for fractionating cells compared to previous works [1], and consequently the separation time, and alleviate any cell clogging problem
