Abstract :
This paper presents the centrifugation using the self-rotating secondary flow in the microchamber. The feasibility of the microfluidic centrifuge was demonstrated numerically an experimentally. The centrifugation of the nano-particles was visualized and its performance was characterized quantitatively. Also, a new finding of the transient motion of the rotating flow influenced the stable operation of the centrifuge.
