摘要

本文采用蚊子法设计和制作了具有三维点阵排列的圆形截面微通道，用于构造开关阀。带有开关阀的三维微通道由两类管线组成:用于化学液体流动的管线和激活阀门的控制线。我们证实，圆形截面和低弹性模量的PDMS用作微通道材料有助于用较低的压力关闭阀门。然后，我们演示了液体流量来评估阀门的功能。将荧光素溶液送入流水线。我们发现，当控制线膨胀关闭流线时，流线和控制线相交处的荧光强度下降，实验证实了通过蚊子方法制备的阀门微通道的功能。

Fabrication of Circular Cross-Section Microchannels with 3-D Lattice Arrangement and Their Use as On-Off Valves

In this paper, circular cross-section microchannels with 3-D lattice arrangements are designed and fabricated using the Mosquito method in order to construct on-off valves. The 3-D microchannels with on-off valves consist of two types of lines: the flow lines for chemical liquid flow and the control lines to activate the valves. We confirmed that both a circular cross-section and a PDMS with low elastic modulus used as the microchannel material contribute to a valve that can be closed with a lower pressure. Then, we demonstrated liquid flow to evaluate the functionality of the valve. Fluorescein solution was flown into a flow line. We found that the fluorescence intensity decreases at the intersection between the flow and control lines when the flow line is closed by the inflation of the control line, experimentally confirming the functionality of the valve microchannels fabricated via the Mosquito method.
