Fig. 2.

Detail design of microfluidic channel with 3 inlets and 2 outlets. The multi-width rectangle channel of d = 5 µm, e = 2 µm and f = 1.5 µm is used for filtration ctDNA from thrombocytes and impurities of plasma input. The ‘g’ represents a curved channel for micromixing of SPM bead particles and targeted particles. The ‘h’ represents a rectangle channel that is used for separation and enhancement of targeted particles by manipulation of a permanent magnet. The entire microchannel is designed with i = 55 mm in length and j = 40 mm in width.
