Abstract
Provided is a microfluidic valve, a method of manufacturing the microfluidic valve, and a microfluidic device that employs the microfluidic valve. The microfluidic valve includes a platform that includes two substrates combined facing each other; a channel having a first depth allowing a fluid to flow between the two substrates; a valve gap that is disposed on at least a region of the channel and has a second depth which is smaller than the first depth; and a valve plug that is disposed to fill the valve gap and is formed of a valve material made by mixing a phase change material, which is solid at room temperature, with a plurality of exothermic particles that emit an amount of heat sufficient to melt the phase change material by absorbing electromagnetic waves.
