Analytical model of the microchip based immunomagnetic assay.
(a) 2D model represents the microchip for rare cells detection. Liquid flow inside the channel follows standard parabolic profile. Cells are released from one side of the channel with uniform initial positions. (b) Magnetic field inside the microchannel generated by the permanent magnets. The area displayed is corresponding to the space inside the microchannel (30 mm × 500 μm).
