Figure 2. Gradient generation in the D2-Chip.
(A) Heat map of the simulated concentration field in the bridge channel, and the parallel gradient channel, source channel and sink channel; (B) Simulated gradient profile in the parallel gradient channel, source channel and sink channel; (C) The fluorescent image of the parallel gradient channel, source channel and sink channel; (D) Gradient profile at different time points in the middle gradient channel. (E) Gradient profiles at two different positions (1000 μm apart) along the middle gradient channel as labeled in (C).
