摘要:
Provided are a microfluidic device and a microfluidic analysis equipment. The microfluidic device includes guides disposed along both edges, a lower plate including a flow path defined between the guides, and a movable upper plate moved along the guides on the lower plate and having a length less than that the flow path. A fluid flow can be simply accurately controlled by adjusting a position of the movable upper plate. As a result, the fluid can sufficiently react in the detection part and the reaction part. Therefore, effective reaction and detection can be realized using only a small amount of fluid, thereby improving sensitivity. In addition, due to the improved sensitivity, a washing process for removing materials that are not consumed in the reaction can be omitted. Also, the movable upper plate can be manually moved using a user's finger.
