Embodiment Construction
[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. However, the invention is not limited to the examples given.
[0029] This embodiment uses a T-tube microfluidic device: insert one end of a polytetrafluoroethylene capillary tube with a length of 5 cm and an inner diameter of 1 mm into one end of a polydimethylsiloxane pipe with an inner diameter of 2 mm and a length of 10 cm to form a T-shaped channel . The other end of the polytetrafluoroethylene capillary was used as the inlet of the continuous phase, one end of the polydimethylsiloxane tube was inserted into a 27G needle as the inlet of the discontinuous phase, and the other end was used as the outlet of the polymer fluorescent microspheres. Use a watch glass filled with the continuous phase solution as a receiving device for fluorescent microspheres, and place it below the outlet end of the polydimethylsiloxane pipeline (such as figure 1 show...
