Microfluidic dialysis module and continuous purification method for drug carriers or biomedicine using the same

A microfluidic dialysis module capable of mass exchange between a first fluid and a second fluid, the microfluidic dialysis module comprising:

• an upper plate having an upper flow path through which the first fluid flows therein formed on one surface thereof, and having an upper inlet through which the first fluid flows into the upper flow path and an upper outlet through which the first fluid flows out of the upper flow path formed on the other surface thereof;
• a lower plate having a lower flow path through which the second fluid flows therein formed on one surface thereof, and having a plurality of lower inlets through which the second fluid flows into the lower flow path and a plurality of lower outlet through which the second fluid flows out of the lower flow path formed on the other surface thereof;
• a membrane disposed between the one surface of the upper plate and the one surface of the lower plate and formed in a porous membrane structure;
• and
• a fixing member coupling the upper plate and the lower plate, wherein a direction in which the first fluid flows in the upper flow path and a direction in which the second fluid flows in the lower flow path are opposite to each other,
• wherein the upper flow path comprises an upper diffusion flow path extending while switching directions at least twice, and the lower flow path comprises a lower diffusion flow path extending while switching directions at least twice,
• wherein the lower flow path comprises a plurality of lower diffusion flow paths, and the plurality of lower diffusion flow paths are formed to be fluidly separated from each other.
