本技术说明描述了对蜡印刷的详细研究，这是一种使用市售打印机和热板在纸上制造微流体装置的简单且廉价的方法。打印机在纸张表面打印固体蜡图案，热板将蜡熔化，使其渗透到纸张的整个厚度。该过程在纸张中形成完整的疏水屏障，限定亲水通道、流体储存器和反应区。每个设备的设计都基于一个简单的方程，该方程解释了熔蜡在纸中的扩散。
This technical note describes a detailed study on wax printing, a simple and inexpensive method for fabricating microfluidic devices in paper using a commercially available printer and hot plate. The printer prints patterns of solid wax on the surface of the paper, and the hot plate melts the wax so that it penetrates the full thickness of the paper. This process creates complete hydrophobic barriers in paper that define hydrophilic channels, fluid reservoirs, and reaction zones. The design of each device was based on a simple equation that accounts for the spreading of molten wax in paper.
