Laser preparation method for microchannels of microfluidic chip

The invention discloses a laser etching preparation method for microchannels of a microfluidic chip. The method comprises the following steps: cleaning the surface of a substrate made from a high-polymer material, so as to remove surface attachments from the substrate; placing the substrate on a mobile platform, etching the substrate by using laser emitted from a gas laser to form microchannels, and meanwhile, measuring out width values of heat-affected zones at two sides of the microchannels; repeatedly carrying out laser etching on the two sides of the microchannels to form microchannels with trapezoidal cross sections, wherein an etched position of last time serves as an origin before each etching, and the mobile platform drives the substrate to transversely translate distances of the width values of the heat-affected zones; and subjecting the laser-etched substrate to annealing treatment, and then, subjecting a cover plate and the substrate to hot-pressing, thereby obtaining the microfluidic chip. According to the method, the trapezoidal microchannels with good morphologies can be obtained by only measuring width values of heat-affected zones of sides after primary etching without complicated calculating and then carrying out etching repeatedly by transversely translating the width values; and the microchannels are flat in bottom face and low in surface roughness.
