Problems solved by technology

[0002] At present, most microfluidic devices are made of quartz, glass or high molecular polymer, the basic structure is shown in the figure, in which 1 is the main channel for the fluid to flow through on the device, and 2 and 3 are the outlets of the main channel (inlet) or inlet (outlet), in this type of device, the fluid can only flow along the plane of the device, and cannot flow in a direction perpendicular to the plane of the device
