Abstract
In the present invention, two adjacent supply lines for supplying two immiscible fluids are spirally disposed on a substrate where microchannels for microsphere production based on a droplet-based highly controlled method for mass-production of microspheres (HCMMM) are formed, and microsphere forming parts each comprising microchannels are arranged between and along the two supply lines, whereby a much larger amount of microspheres can be produced. Further, the two supply lines are disposed in a spiral configuration, and the microsphere forming parts can be disposed by branching microchannels from the two supply lines on inner and outer sides of the spiral configuration, whereby the limited space on a wafer normally having a circular shape can be maximally used to form multiple microsphere forming parts.
