US 2022/0032303 A1 · MICROFLUIDIC MIXER AND MICROFLUIDIC DEVICE COMPRISING THE SAME

Abstract

The present invention relates to a microfluidic mixer and a microfluidic device including the same, and in the microfluidic mixer according to the present invention, a disk-shaped mixing unit with double U-shaped protruding portions formed therein can be continuously provided along a microchannel, thereby increasing collisions of samples to improve the binding efficiency thereof and shorten the binding time. Furthermore, the microfluidic device according to the present invention can detect a target material at high speed even at a high flow rate by including the microfluidic mixer, and thus can be usefully utilized for early diagnosis and prognosis diagnosis of a disease such as cancer.

Dependent claims

A microfluidic mixer comprising:

a first microchannel with a first inlet and a second inlet, through which a fluid is introduced, being formed on one side and a first outlet, through which the fluid is discharged, being formed on the other side;
and
at least two or more disk-shaped mixing units disposed between the first inlet and second inlet and the first outlet,
wherein a U-shaped first protruding portion and second protruding portion protruding from the disk surface are formed in the mixing unit and
the first protruding portion is disposed inside a curved portion of the second protruding portion.
