摘要： A microfluidic device and a method of fabricating the microfluidic device are provided. The microfluidic device includes: a platform including an upper substrate and a lower substrate that are bonded to face each other; a microfluidic structure obtained by forming grooves in the lower substrate; a lower substrate protrusion pattern including an outline protrusion that protrudes from the lower substrate toward the upper substrate along an outline of the microfluidic structure; and an adhesive layer disposed between the lower substrate protrusion pattern and the upper substrate in order to bond the upper substrate and the lower substrate to each other. The lower substrate protrusion pattern only supports the upper substrate, and remaining portions of the lower substrate except for the lower substrate protrusion pattern do not have structures for supporting the upper substrate.

摘要： Provided are a valve unit, a microfluidic device including the same, and a method of fabricating the valve unit. The method includes: forming a lower substrate including a channel including a first region and a second region which is deeper than the first region and is adjacent to one side of the first region; forming an upper substrate comprising a valve material chamber which extends only partially through the upper substrate; filling the valve material chamber with a valve material and curing the valve material in the valve material chamber; attaching a surface of the upper substrate in which the valve material chamber is formed to a surface of the lower substrate in which the channel is formed, so that the valve material chamber overlaps an overlapped portion of the first region, and does not overlap a non-overlapped portion of the first region; melting the valve material accommodated in the valve material chamber to flow the valve material into the non-overlapped portion of the first region; and curing the valve material flowed into the non-overlapped portion to close the first region.
