Abstract: The present disclosure relates to a microfluidic bubble trap for blocking or removing bubbles introduced inside a chip in the process of sensing, a separation, a measurement, an incubation, and an analysis based on the microfluidic technology and preventing a flow of fluid in a channel from being hindered or preventing bubbles from occupying the fluid, so that the functional efficiency in an operation such as a sample analysis, a sample separation, a measurement, and the like may be significantly improved. The present disclosure provides a microfluidic bubble trap including a trap body for separating bubbles and the microfluid is introduced therethrough; a microfluid inlet connected in a first direction of the trap body and supplying the microfluid; and a microfluid outlet installed through an upper portion of the trap body and an end of a channel is disposed in a lower portion of the microfluid inlet.

Abstract: The present invention relates to a disposable separation chip used when separating magnetic beads present in a mixed solution using magnetic force. The present invention provides disposable separation chip including a lower chip on which a wire pattern having a parabolic shape from one side to another side thereof is formed; and a separation chip separable from the lower chip, wherein the separation chip includes: an upper plate on which a coupling portion coupled to a tubing is formed; and a first member disposed under the upper plate and coupled to a lower surface of the upper plate, wherein the coupling portion is integrally produced with the upper plate wherein it is formed through the upper surface and the lower surface of the upper plate to be connected to a channel.

Abstract: An optical imaging system includes a first lens having a convex image-side surface, a second lens having a concave object-side surface, a third lens, a fourth lens, and a fifth lens disposed sequentially from an object side. The optical imaging system satisfies 4.8<f/IMG_HT<9.0, where f is a focal length of the optical imaging system, and IMG_HT is half a diagonal length of an imaging surface of an image sensor.

Abstract: The present invention relates to a system and method for cell separation. The system includes: a cartridge having a polygonal shape in cross section and including an injection part, a separation chip separating a flow channel of a sample injected through the injection part, and a discharge part; and a base plate coupled to the cartridge through its upper surface and including a magnetic chip for cancer cell capture, liquid sensors, and valves.
