Embodiment 1
[0026] (1) Prepare the silicon positive mold template for the polydimethylsiloxane microfluidic chip by soft etching;
[0027] (2) winding 40 turns of enamelled copper wire on an iron core with a diameter of 1mm to make a microcoil (4), wherein the diameter of the enamelled copper wire is 0.1mm;
[0028] (3) Two 40-turn microcoils (4) are fixed on both sides of the microchannel on the silicon positive mold template, the angle between the coils is 120°, and the plane formed by the two coils and the plane of the template are clamped. The angle is 60°;
[0029] (4) Mix the polydimethylsiloxane monomer and the curing agent in a ratio of 10:1, stir thoroughly, remove air bubbles and pour it on the silicon positive mold template for fixing the microcoil, and cure at 80°C for 3 hours, Then the cured polydimethylsiloxane is peeled off from the silicon positive mold template to make a chip substrate with microcoils (4) and microchannels (3);
[0030] (5) Punch holes on the chip subst...
