In this paper, we propose a novel approach to fabricate fluidic chips. The method utilizes molecular cross-diffusion, induced by photopolymerization under ultraviolet (UV) irradiation in a channel pattern, to form the channel structures. During channel structure formation, the photopolymer layer still contains many uncured molecules. Subsequently, a top substrate is attached to the channel structure under adequate pressure, and the entire chip is homogenously irradiated by UV light. Immediately thereafter, a sufficiently sealed fluidic chip is formed. Using this fabrication process, the channel pattern of a chip can be designed quickly by a computer as binary images, and practical chips can be produced on demand at a benchtop, instead of awaiting production in specialized factories.

一种基于光聚合的交叉扩散的流体芯片按需台式制造工艺。

在本文中，我们提出了一种新颖的方法来制造流体芯片。该方法利用了在紫外（UV）辐射下以光聚合在沟道图案中引起的分子交叉扩散来形成沟道结构。在通道结构形成期间，光敏聚合物层仍包含许多未固化的分子。随后，在适当的压力下将顶部衬底附接到沟道结构，并且用UV光均匀地照射整个芯片。此后立即形成充分密封的流体芯片。使用这种制造工艺，可以通过计算机快速将芯片的通道模式设计为​​二进制图像，并且可以根据需要在台式机上生产实用的芯片，而不必等待专门工厂中的生产。
