Microfluidic is a fine art of creation and manipulation of small portions of fluids. This method allows us the production of polymer beads whose properties can be adjusted by varying the parameters and composition. Microfluidics consists of a pump system and a microfluidic chip. At the end of microfluidics, different types of devices can be added (UV Irradiation, Cryo or heating systems). The polymer beads are then used in biomedical applications.
