Figure 9. Concentration profiles in the large drop regime. The profiles of P (red curve) and S (blue curve) are flat and therefore at chemical equilibrium far from the interface (Pin(0), Pout(∞)). Concentration gradients of length scale ξ (Eq. (11)) are localised at the interfacial region only. Hence the reaction-diffusiondriven circulation of molecules P and S between drop and cytoplasm (blue↔red circular arrow) is also localised at the interfacial region only. See Fig. 7 for details about this circulation.
