On the other hand, smaller channels have greater chances of being easily clogged if the particles sorted are too many. Therefore, in our design, we opted for a channel size of 2 mm and a lateral step size of 0.5 mm, which is an ideal compromise between avoiding quick clogging and reducing deformability under pressure. We have also designed a chip with 5 parallel channels for avoid fast clogging when using high concentration of particles (Figure ). This microfluidic device was designed to be cheap, easily fabricable, and for being suitable to be used in the field. Some compromises were inevitable.
