Abstract

In this work a portable microfluidic device with a reusable integrated high voltage power supply is presented, which allows for quick exchange of inexpensive disposable poly(dimethylsiloxane)(PDMS) microfluidic chips on a carrier only slightly larger than a microscope slide. The device is powered by an onboard MN21 cell battery (5 mm radius, 30 mm long) and is demonstrated through the rapid and controlled transport of a fluorescent dye through an expansion chamber geometry. Power consumption experiments demonstrate the device's ability to complete over 40 dispense-flushing cycles on a single battery.

摘要

在这项工作中，展示了一种带有可重复使用集成高压电源的便携式微流控装置，该装置能够在仅比显微镜载玻片略大一点的载体上快速更换廉价的一次性聚二甲基硅氧烷（PDMS）微流控芯片。该装置由一个板载MN21电池（半径5毫米，长30毫米）供电，并通过荧光染料在扩展腔几何结构中的快速且可控传输进行了演示。功耗实验证明了该装置在单节电池上能够完成超过40次分配 - 冲洗循环的能力。
