Problems solved by technology

As the core tool of microfluidic technology, microfluidic chip belongs to an important technical branch in the field of microelectromechanical technology. Microfluidic detection chip has the advantages of less sample consumption, fast detection speed, easy operation, multi-functional integration, small size and portability. It can be widely used in biological, medical, chemical and other technical fields. In the existing technology, the microfluidic chip has a single structure and function, and does not have functions such as automatic detection and sorting, which leads to limited application scenarios and restricts its development.
