Caption: To demonstrate this concentration gradient generator, created in the lab at SEAS, two dyes are injected at the top, and they travel through a maze of tiny channels. The configuration of the channels, the flow rate of the dyes, and the material properties of the chip all affect the amount of mixing that can take place. At the end of the maze, a predictable concentration gradient is produced.
