Proliferation and viability of COS-7 cells trapped by standing-wave ultrasound in a microfluidic chip

• We study cell viability after ultrasonic-standing-wave trapping of low cell numbers in a microfluidic chip by recultivation of the trapped cells. The cell proliferation rate is estimated by counting of initial and final cell numbers and shows normal cell growth. The results demonstrate the potential of ultrasonic standing waves as a tool for gentle and long-term manipulation of low cell numbers in microfluidic systems.
