PFF devices have been previously developed for the size-dependent separation of particles, either by pressuredriven [1,2] or centrifugal [3] pumping. In the present study, we employed centrifugal force as the means both for the fluid transportation and particle migration perpendicularly to the flow direction, which enable particle separation based on size and density. In the experiment, microparticles with different densities were successfully separated by employing the centrifugal pumping. The presented microfluidic system is useful and versatile due to its accuracy and simplicity in operation.Read More
