聚二甲基硅氧烷（PDMS）是一种重要的功能材料，在科学研究、工业生产、医疗器械、整形外科等领域有着广泛的应用。所制备的微通道具有圆形横截面形状，光滑的内表面，直径从100 μ m到9 μ m。我们证明，这些微通道可以应用于构建复杂的，三维（3D）结构的双螺旋，结，以及互连沿着不同的方向。结合PDMS本身的优点，这种灵活和通用的技术在先进的3D微流体器件和生物系统中的嵌入式器件中显示出很好的应用潜力。(C)2015爱思唯尔有限公司版权所有。
Polydimethylsiloxane (PDMS) is an important functional material that has been intensively applied in science research, industry, medical devices, plastic surgery, etc. We presented here a new method of fabricating small diameter microchannels in PDMS without using standard cleanroom techniques such as lithography and etching. The as-fabricated microchannels had a round cross-sectional shape, smooth inner surface, and a diameter from 100 mu m down to 9 mu m. We demonstrated that these microchannels could be applied to construct complicated, three-dimensional (3D) structures of double helix, knots, as well as interconnection along different directions. Together with the merits of PDMS itself, this flexible and versatile technique showed a promising potential for applications in advanced 3D microfluidic devices, and embedded devices in biosystems.
