Abstract
We introduce a flow regulating technology that uses trapped air bubbles in a hydrophobic microfluidic channel. We present basic designs for flow regulators and flow valves using trapped air. Experiments have successfully demonstrated the capability of this technique for delivering constant and varying flow rate, and for on-off valving. This approach to valving provides a simple, yet effective way to monolithically integrate flow and valve control on polymer Lab-on-Chip devices.
摘要
我们介绍了一种利用疏水性微流体通道中捕获的气泡的流量调节技术。我们展示了使用捕获空气的流量调节器和流量阀的基本设计。实验已成功证明了该技术在输送恒定和变化流速以及通断阀控方面的能力。这种阀控方法为在聚合物芯片实验室设备上整体集成流量和阀控提供了一种简单而有效的方式。
