Figure 5

(a–c) The top view of the flow dyed with pigments in different flow rates, the flow rates are (a) Q₁ = Q₂ = Q₃ = Q₄ = 1 μl/min, (b) Q₁ = Q₂ = Q₃ = Q₄ = 12.5 μl/min, (c) Q₁ = Q₂ = Q₃ = Q₄ = 95 μl/min. (d–f) show the light path dyed with rhodamine (6 g) in different flow rates corresponding to the (a–c). The dotted line denotes the wall of the microchannel and the intensity measurement line of the fluorescent. (g) The comparison intensity curve in the “D” point with dependence of on – off state.
