提出了一种基于喷墨打印液体模板制备微通道的简单方法。通过使用粘度对温度敏感的油墨可以很好地控制液体模板的形态。所制备的Y形微通道被用作微流控反应器，在聚二甲基硅氧烷（PDMS）基质中进行酰化荧光反应。在微通道形成的同时，可以方便地实现微通道的任意变形。通过将聚乙二醇（PEG）接枝到内表面上，获得抗生物吸附的微通道。该方法简便易行，对功能修饰微流控芯片的制作具有重要意义。
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.
