Abstract
A microfluidic disk includes: a disk-shaped main body; an injection port; a distribution channel; measuring vessels; microvalves; a wastewater container; and holding containers.
Claims6
A microfluidic disk comprising:
- a disk-shaped main body that rotates by itself on its central axis along a rotational direction;
- an injection port that is formed on the disk-shaped main body and receives fluid from outside;
- a distribution channel that extends from the injection port along the rotational direction while maintaining a predetermined distance from the central axis, and allows the fluid to pass therethrough;
- measuring vessels that extend from the distribution channel toward the edge of the disk-shaped main body, and hold a predetermined volume of the fluid;
- microvalves that are connected to ends of the measuring vessels and controlled to be opened and closed by rotational angular velocity of the disk-shaped main body;
- a wastewater container that is connected to ends of the distribution channel and holds the fluid;
- and
- holding containers that are connected to the microvalves and positioned between the distribution channel and the edge of the disk-shaped main body, and hold the fluid that has passed through the microvalves.
