A simple method to fabricate microchannels is demonstrated based on an inkjet printing liquid template. The morphology of the liquid template can be well controlled by using ink with viscosity sensitive to temperature. The as-prepared Y-shape microchannel is used as a microfluidic reactor for an acylation fluorigenic reaction in a matrix of polydimethylsiloxane (PDMS). Arbitrary modification of the microchannels could be easily realized synchronously with the formation of the microchannels. By grafting polyethylene glycol (PEG) onto the internal surface, an anti-biosorption microchannel is obtained. The facile method will be significant for the fabrication of a microfluidic chip with functional modifications.
一种基于喷墨打印液模板制备微通道的简单方法得到了展示。通过使用对温度敏感的粘性油墨，可以很好地控制液体模板的形态。所制备的 Y 型微通道可用作聚二甲基硅氧烷（PDMS）基质中酰化荧光反应的微流控反应器。微通道的任意修饰可以与微通道的形成同步轻松实现。通过在内部表面接枝聚乙二醇（PEG），获得了抗生物吸附的微通道。这种简单的方法对于制备具有功能修饰的微流控芯片具有重要意义。
