Microfluidic technology has attracted great attentions owing to its huge functions which have obviously promoted the rapid development of frontier technologies in the research areas of biology, chemistry, medicine, fluid, electronics, materials and machinery, and so on. On this basis, it is of great significance to develop simple and convenient assembling protocols for the preparation of multibranched microfluidic tubes that are the critical elements for construction of more complex microfluidics systems. This project thus aims at development of an "one-step" reaction to convert hydrogel films into microfluidic tubes. We will mainly focus on the constructing process to explore the conversion mechanism from hydrogel membrane to microfluidic tubes. In the meantime, a lot of tests will be carried out to demonstrate the potentials of prepared microfluidic tubes on control over the complex microfluidics systems, which are expected to be promising for real-world applications. The purpose of this project is to finally solve the issues that at present are hindering the developments of microfluidic systems. We believe that the exploration of this project would provide serviceable theories and protocols for complex multibranched microfluidic systems.
