Problems solved by technology

And as the complexity of the gradient generator network increases, its design difficulty also doubles
[0004]At present, the design method of microfluidic dilution network is mainly based on the experimental improvement method. Due to the complexity of the fluid characteristics, this method of relying on experience and experimental modification design is not suitable for microfluidic dilution networks. With the development of large-scale integration of fluidic technology, if you want to design a highly integrated microfluidic dilution network chip with complex functions, it is difficult to achieve it only by experimental methods, and the experimental cost is relatively high
