Cell separation device using ultrasound and electrophoresis

摘要

A cell separation module for separating and collecting cells having a charge and cells having no charge comprises a holder and a throwaway cell separation chamber held by the holder. Ultrasound is introduced into the cell separation chamber so as to allow force for causing cells to be put together to act into the cell separation chamber. In addition, an electrostatic force is allowed to act in the cell separation chamber so as to cause the cell to move by the charges of the cells. Competition between both the forces is used to separate the cells correspondingly to the freshness of the cells.
