FIG. 3.

Size separation of polydispersed microbeads in the centrifugal microfluidic device. (a) Graph shows the relationship between the separation efficiency of mixed particles and its size resolution. Inset denotes the schematic diagram of the size separation within the microfluidic channel. (b) Representative images of the oligosuspended particles in the microfluidic channel after centrifugation, larger particles are outlined in red, smaller particles are outlined in green. Scale bar denotes 100 μm.
