| 摘要 |
The present invention relates to a microfluidic chip with an inclined channel wall which comprises: a first channel unit; a sample inlet and a buffer inlet which are connected to one end of the first channel in parallel; a second channel unit which has a wider channel width than that of the first channel unit, and in which one end is linearly connected to the other end of the first channel; and a plurality of particle outlets which are connected to the other end of the second channel unit in parallel. In the first channel unit, a channel wall in the sample inlet side has a stereoscopic shape in the height direction in order to arrange target dividing particles inside the sample fluid injected through the sample inlet according to the size and shape. By discharging the sample fluid flowed into the first channel unit, the microfluidic chip for arranging and separating micro particles, which additionally includes one or more damping channels which enhances the array and separation efficiencies of the particles, is provided to the channel wall in the sample inlet side of the first channel having stereoscopic shape. The microfluidic chip of the present invention can only separate the micro particles by size or shape by simple channel structure changes so that the microfluidic chip can be used to expand the application range of the microfluidic chip. |
