The present invention may provide a microfluidic device including a rotatable body; a first chamber positioned in a direction of an inner wall of the body; a second chamber positioned in a direction of an outer wall of the body from the first chamber; and a backflow prevention unit, and wherein a fluid is transferred from the first chamber to the second chamber, and wherein the backflow prevention unit prevents a backflow of the fluid from the second chamber to the first chamber.

Microfluidic device

The present invention relates to a centrifugal force-based nanoparticle separation apparatus and method. Specifically, the present invention is based on having a low centrifugal force and a small size, and may thus separate nanovesicles unrelated to antibody specificity in a short time and without using an ultracentrifuge. Further, the present invention requires no additional professional personnel and enables accurate fluid measurement by integrating and automating all processes after sample injection, and may thus reduce the loss of nanovesicles.

A particle filtering device which shortens the separation time of particles and increases the separation efficiency are provided. The particle filtering device comprises: a filtration membrane which separates a particle by filtering a sample; a first body connected to an inlet side of the filtration membrane, which supplies the sample to the inlet side of the filtration membrane; and a second body connected to an outlet side of the filtration membrane, which accommodates a permeate whose particle is separated through the filtration membrane, wherein the particle filtering device has a structure in which the permeate is accommodated in advance between the second body and the outlet side of the filtration membrane.

Particle filtering device and method

Provided is a microfluidic device to more easily and mechanically operate a valve for controlling a fluid flow, which comprises: a platform having a plurality of chambers; at least one flow channel which connects between the chambers; and a valve which opens or closes the flow channel, wherein the valve includes a blocking member which selectively blocks the flow channel and a pressing member installed in the blocking member to move the blocking member, and the pressing member has a structure which presses and moves the blocking member by the linear reciprocating motion in the same direction as the direction of an external force, and the valve further includes a driving unit which reversibly controls the opening and closing of the flow channel caused by the blocking member by fixing the pressing member to the position of the moved pressing member or returning to the original position.
