Microfluidic multi-well-based cell culture testing device

A microfluidic multi-well-based cell culture testing device that has an array structure of a plurality of aligned microfluidic well units, each of the microfluidic well units comprising

• an inlet comprises a recess, wherein the recess is exposed to air in an upward direction such that a first fluid is injected into the inlet from a top of the recess,
• an accommodation compartment adapted to accommodate a second fluid therein,
• a microfluidic channel through which the first fluid flows, and
• an air outlet adapted to facilitate the entering of the first fluid, wherein the air outlet
• comprises a second recess and is in direct contact with one end of the microfluidic
• channel, the inlet is in direct contact with another end of the microfluidic channel, and the
• air outlet is not in direct contact with the inlet,
• wherein the accommodation compartment is designed in the form of a well such that the entering second fluid is retained, and a capillary valve is formed where a portion of the lower lateral side of the accommodation compartment is in communication with a portion of the lateral side of the microfluidic channel such that the first fluid and the second fluid meet each other to form an interface, and
• the inlet and the accommodation compartment are spatially separated from each other and does not directly contact each other.
