Abstract:
1. A microfluidic device comprising: a platform comprising a chamber configured to accommodate a fluid therein, the chamber comprising: an inner sidewall; an outer sidewall disposed outwardly from the inner sidewall in a radial direction of the platform; and a bottom surface, wherein the outer sidewall includes a first point located closest to a center of the platform, a second point located farthest from the center of the platform, wherein the chamber further comprises an exit provided at the second point for outflow of the fluid accommodated in the chamber, wherein the bottom surface is inclined upward to the exit, and wherein a distance from the inner sidewall to an arbitrary third point on the outer sidewall between the first point and the second point increases in a radial direction from the first point to the second point, so that the fluid near the first point is guided to the second point by centrifugal force during rotation of the platform.
