Abstract
A microfluidic device comprising a first substrate including a micro-flow path and a valve seat protruding into the micro-flow path, a second substrate coupled to the first substrate and including a cavity aligned with the valve seat, and a valve gate film provided between the first substrate and the second substrate, such that the valve gate film opens and closes the micro-flow path with air pressure applied to the cavity, wherein a surface of the valve seat is separated from the valve gate film at the initial stage such that the micro-flow path is opened at the initial stage, and the valve gate film moves to be in contact with the surface of the valve seat so that the micro-flow path is closed when air pressure is applied to the cavity.
