[0022] Example 1
[0023] The present invention proposes a method for manufacturing a microfluidic chip based on the nanofiber template method. The method includes: first placing a receiving plate 2 on a three-dimensional motion platform 3, following the motion platform 3 for three-dimensional motion, and placing the motion platform 3 and the receiving plate 2 on the mounting plate. In the container with the liquid light-curing material 4, make the liquid light-curing material 4 pass the receiving plate 2 for a certain distance, and turn on the surface light sources 6 distributed on both sides of the spinning nozzle 1 to solidify the liquid light-curing material above the receiving plate 2 , Forming a microfluidic chip substrate. The soluble polymer solution / melt is passed through the spinning nozzle 1 for near-field electrospinning or microflow spinning, and the order of the fibers on the receiving plate 2 is achieved by controlling the relationship between the falling speed of ...
