Abstract

A new method for prototype of a three dimensional (3 D) microfluidic device on piezoelectric substrate was presented. Wires were stick by colloidal starch, and dried in a thermotank for three dimensional channels mold. The mold was slightly placed in a groove with poly(dimethylsiloxane). After having been solidified, these wires were drawn off to form 3 D microchannels. Surface acoustic wave was used to driven sample droplet to the inlet of the microchannel in microfluidic device. Red fluid transportation in different microchannels was successfully demonstrated using the 3 D microfluidic device at 24.5 dBm signal power for verifying the function of the microfluidic device.

压电基体上聚二甲基硅氧烷中三维微流体体系的制备

摘要

提出了一种在压电基片上制作三维(3D)微流体器件原型的新方法。线被胶态淀粉粘住,并在热槽中干燥以用于三维通道模具。将模具稍微放在带有聚二甲基硅氧烷的凹槽中。固化后,将这些金属丝引出以形成3D微通道。使用表面声波将样品液滴驱动到微流控设备中的微通道入口。使用3D微流体设备以24.5 dBm的信号功率成功证明了在不同微通道中的红色流体运输,以验证微流体设备的功能。
