[0021] Further describe the present invention below by embodiment and accompanying drawing:
[0022] 1. Cyclopentanone-assisted hot-press packaging of polymethyl methacrylate microfluidic chips
[0023] (A) The design of the microfluidic chip uses Adobe Illustrator 10.0 software to design the microfluidic channels and solution connection holes of the chip, and uses a high-resolution (3600dpi) laser phototypesetting system to print a mask negative on a polyester transparent film. The width of the microfluidic channel is 50 μm, and the solution connection hole is a circular hole with a diameter of 2 mm, in which the microfluidic channel (separation capillary 2 and sampling capillary 7) and solution holes 1, 4, 5 and 6 (Fig. 1) are transparent, and the remaining Part is black. The positive image of the microfluidic chip is shown in Figure 1. The separation microfluidic channel 2 is 5.0 cm long, and the sampling microfluidic channel 7 is 0.5 cm long, and the distance from the in...
