Abstract
A microfluidic device includes a lower casing and an upper casing covering the lower casing. The lower casing includes a lower base wall having a top surface and a plurality of spaced-apart columns that protrude upwards from the top surface. The upper casing includes an upper base wall. A first gap between the upper base wall and a column top surface of each of the columns is large enough to permit passage of large biological particles of a liquid sample, and a second gap between any two adjacent ones of the columns is not large enough to permit passage of the large biological particles and is large enough to permit passage of small biological particles of the liquid sample.
