Figure 2.

Illustration of forces utilized to control fluids on centrifugal microfluidic platforms, including the centrifugal force (F${}_{\omega }$), Coriolis force (F${}_C$) and Euler force (F${}_E$). Kinematic quantities (blue) and forces (red) are shown for a fluid element moving at a velocity (u) on a portion of a disc at a distance $\overline{r}$ from the center of the disc.
