目前的微流控纸基设备缺乏用于流体操作的关键部件。我们创造了一种完全在单层纸上制造的流体二极管，以控制液体的芯吸。流体二极管是一种两端组件，可促进或阻止沿纸张通道的芯吸。在此基础上，进一步构建了触发器和延迟阀。此外，我们还演示了一个高级功能电路，由一个二极管和一个延迟阀组成，以连续的方式操作两种流体。我们的研究提供了新的、变革性的工具来操纵微流控纸基设备中的流体。
Current microfluidic paper-based devices lack crucial components for fluid manipulation. We created a fluidic diode fabricated entirely on a single layer of paper to control the wicking of fluids. The fluidic diode is a two-terminal component that promotes or stops wicking along a paper channel. We further constructed a trigger and a delay valve based on the fluidic diode. Furthermore, we demonstrated a high-level functional circuit, consisting of a diode and a delay valve, to manipulate two fluids in a sequential manner. Our study provides new, transformative tools to manipulate fluid in microfluidic paper-based devices.
