To determine the effect of viscosity in the simulations, the single-chain folding and multi-chain aggregation time scales were calculated for a system with Langevin friction coefficient 1/10th the value used for all other simulations in implicit DCB. The measured time constants for single-chain folding (τ s ) and multi-chain aggregation (τ c ) are given alongside the DCB-viscosity results in Table . Both the single-and multi-chain aggregation time scales were found to scale approximately linearly with γ, indicating that while viscosity will change τ c and τ s , it will do in such a way that it is not expected to change the calculated value of c † . Indeed, the low-viscosity system is included as one the 20mer points in Fig. and shows roughly the same scaling of c † with N as the higher viscosity points.
