受動バルブを用いたスラグ液滴の自動格納マイクロ流体デバイス

抄録

We developed an automatic slug storage microfluidic device using hydrophobic passive valves. In order to measure temporal concentration change of cutaneous anesthesia with high temporal resolution, we previously developed a slug flow device, which can automatically split solutions into small droplets, and suppress mixing old and new solutions just within a slug. However, the many droplets should be stored in different reservoirs without fusing them together. For this purpose, automatic slug storage microfluidic device was necessary, and we achieved the device by using hydrophobic passive valves with different pressure barriers. Using this device, slugs were automatically stored in different reservoirs.
