Microfluidic Concentration Gradient Chip

In microfluidic chip-channel networks, the fluid is mainly laminar, so that when two or more different reagents flow into the same channel, the reagents can maintain their flow patterns unchanged and only occur at the phase-to-phase contact Reaction or molecular diffusion, the concentration gradient formed has high stability and reproducibility, and a series of complex concentration gradients can be obtained by changing the configuration design of the channel network and the initial flow concentration and combination order, utilizing Microfluidic concentration gradient chip can simulate the external environment, the establishment of chemical concentration gradient, at the cell and individual level to study organisms on the external environment changes in response. The technology has been widely used in drug screening, biochemical chemotaxis, toxicity and other research areas.
