Development of multi-step micro-channel device for component separation

Abstract

The motivation for this research is to propose a method that facilitates the blood separation process, which is originally performed by a centrifuge, with a chip-type device. The motivation for this research is to propose a method that facilitates the blood separation process, which is originally performed by a centrifuge, with a chip-type device. A separation test between micro-beads and liquid was performed using a suspension of polystyrene micro-beads simulating erythrocytes. Finally, we succeeded in extracting only the liquid component by physically trapping the microbeads using the step of the micro-channel. In this study, we report on the design and separation performance of micro-channels.
