Patent ID: 8119079

Claim:
microfluidic apparatus comprising: a substrate including at least one channel; a fluid container in which at least one kind of fluid is accommodated and which is disposed on the substrate so as to allow the fluid to flow toward the channel; a fluid flow controller which controls a flow of the fluid toward the channel from the fluid container; wherein the fluid container is attached to the substrate to be rotated or slid on the substrate, and the fluid flow container comprises a container lid which prevents arbitrary outflow of the fluid accommodated in the fluid container; wherein the substrate comprises an explosion unit which explodes the container lid by contacting the container lid when the fluid container is rotated or slid on the substrate; wherein the fluid flow controller comprises a valve formed of a phase transition material that closes the channel, wherein the fluid flow controller is melted by an energy of an electromagnetic wave to open the channel; wherein the valve further comprises a plurality of microheating particles which are dispersed in the phase transition material and that absorb an energy of an electromagnetic wave to dissipate heat; and wherein the fluid container is attached to an upper surface of the substrate such that the fluid container is provided on top of the substrate.
