In the inset of Fig. , we plot the model-predicted microgel net charge versus c mic , which decreases with increasing concentration as expected. From static light scattering experiments, the experimental net charge for the swollen microgels is |Z net | ≈ 300, which is 2 orders of magnitude smaller than Z max . On the other hand, the averaged Z net from theory is one order of magnitude smaller than the experimental Z max , which qualitatively agrees with the trend of the experiments and proves the net charging of microscopic networks and the heterogeneous distribution of microions between inside and outside of the counterions. The quantitative difference in Z net is in agreement with the overestimation of Z net already observed in the simulations. We notice then that the approximate nature of both coarse-grained models, namely electrostatic and gel parts, lead observables to acquire values that may differ from the experimental ones, but maintaining overall consistency and qualitative agreement with further system observables and parameters.
