本文介绍了三维微流控纸基分析装置（3-D亩PAD），可以编程（后制造）由用户产生多种模式的流动通过它们。这些设备通过使用手写笔或圆珠笔按下一次性“打开”按钮进行编程。按下按钮关闭两个垂直对齐的微流体通道之间的小空间（间隙），并允许流体从一个通道芯吸到另一个通道。这些设备制作简单，完全由纸和双面胶带制成。可编程器件扩展了μ PAD的功能，并提供了一种简单的方法来控制纸基通道中的流体运动。它们在概念上等同于广泛应用于电子领域的现场可编程门阵列（FPGA）。
This paper describes three-dimensional microfluidic paper-based analytical devices (3-D mu PADs) that can be programmed (postfabrication) by the user to generate multiple patterns of flow through them. These devices are programmed by pressing single-use 'on' buttons, using a stylus or a ballpoint pen. Pressing a button closes a small space (gap) between two vertically aligned microfluidic channels, and allows fluids to wick from one channel to the other. These devices are simple to fabricate, and are made entirely out of paper and double-sided adhesive tape. Programmable devices expand the capabilities of mu PADs and provide a simple method for controlling the movement of fluids in paper-based channels. They are the conceptual equivalent of field-programmable gate arrays (FPGAs) widely used in electronics.
