Paper-based microfluidic devices offer an ideal platform for biological and environmental detection because they are low-cost, small, disposable, and fill by natural capillary action. In this tutorial review, we discuss the surface modification of paper-based microfluidic devices with functional polymers using the initiated chemical vapor deposition (iCVD) process. The iCVD process is solventless and therefore ideal for coating cellulose paper because there are no surface tension effects or solvent compatibility issues. The process can also be scaled up for roll-to-roll manufacturing. The chemical functionality of the iCVD coating can be tuned by varying the monomer and the structure of the coating can be tuned by varying the processing parameters.

通过引发化学气相沉积对纸基微流控器件进行表面改性


纸基微流控设备为生物和环境检测提供了理想的平台，因为它们成本低、体积小、一次性且通过自然毛细管作用填充。在本教程回顾中，我们讨论了使用引发化学气相沉积 （iCVD） 工艺对具有功能聚合物的纸基微流体器件进行表面改性。iCVD 工艺是无溶剂的，因此非常适合涂布纤维素纸，因为没有表面张力效应或溶剂兼容性问题。该工艺也可以扩大规模，用于卷对卷制造。iCVD 涂层的化学功能可以通过改变单体来调整，涂层的结构可以通过改变加工参数来调整。
