To investigate how the monomer-monomer interaction strength affects such collective structural/dynamical equilibrium, we compared simulations with increasing interaction strength (ε) between the monomer core beads: ε = 40 kJ mol -1 , ε = 45 kJ mol -1 and ε = 50 kJ mol -1 . As shown in Figure , at the dynamical equilibrium state the assembly size-distribution is globally conserved (insets), while molecular entities are continuously exchanged between the assemblies (details on the equilibration are reported in Figures ).
