An innovative fabrication method is presented that affords the combination of polydimethyl-siloxane (PDMS) microfluidic technology with vibrational spectroscopy. PDMS devices are produced with uniform thicknesses ranging from 25 to 400 μm. The optical characteristics of the microfluidic devices in the mid-infrared are reported. The broad utility of this approach is demonstrated through IR imaging of flows in functional gradient generators and flow-focusing devices.
本文提出了一种创新的制造方法,将聚二甲基硅氧烷(PDMS)微流控技术与振动光谱相结合。PDMS 器件的厚度均匀,范围从 25 到 400 μm。报道了微流控器件在中红外光下的光学特性。通过在功能梯度发生器和流聚焦装置中对流动进行红外成像,证明了这种方法的广泛适用性。
