(a) Snapshots of a microgel particle exhibiting the typical volume phase transition from swollen to compact. (b) Numerical form factors, averaged over four different realizations, for microgels with N ∼ 41 000 monomers and c = 3.2% of cross-linkers generated in a sphere of radius Z = 30σ (symbols) at different values of the solvophobic parameter α, corresponding to the reported temperatures as obtained from the swelling curve comparison to experiments in Figure 6. Solid lines are fits of the curves using the fuzzy sphere model of eq 6. (c) Averaged density profiles obtained from MD simulations of a microgel with N ∼ 41 000, c = 3.2%, and Z = 30σ (symbols) and from the fit of the form factors using the fuzzy sphere model (solid lines).
