Embodiment 1
[0067] The microfluidic chip of the present invention is a three-layer structure, including the upper and lower PDMS membranes and the middle dialysis membrane layer. There are grooves on the PDMS membrane, and the grooved surfaces of the upper and lower membranes are bonded to the dialysis membrane to form an upper and lower membrane. Two microfluidic channels; the channels have an equal depth of 50 μm throughout. The horizontal cross-sectional shape of the microfluidic channel in the lower layer is in a mirror image relationship with the horizontal cross-sectional shape of the upper layer channel. The channels are arranged in a longitudinal serpentine shape on the diaphragm: the serpentine channel in the adjustment section has 3 bends, the width is 2mm, the vertical part of the channel is 7mm long, and the diameter of the semicircle of the curved part is 4mm; the shearing section has 3 Each bend has a width of 150 μm, the length of the vertical part of the serpentine channel...
