Fig. 5. Finite element simulations of concentration profiles for a 10 mM [Ru(bpy)3]2+ bulk concentration in the nanochannel. Two-dimensional [Ru(bpy)3]2+ profiles in (a) redox cycling mode, and (c) annihilation mode. (b and d) Corresponding cross-sectional profiles in the channel center (indicated by the dashed line in both modes, respectively).
