SANS form factors and corresponding fits; green asterisks, monodisperse small-only sample at ; purple diamonds, bidisperse sample with %, , and a radius nm of the deswollen small particles; black plus signs, monodisperse sample at with 115.3 mM NaSCN; and red triangles, same as black plus signs but without NaSCN salt. See Table S1 for fully swollen particle radii. The fit for the black plus signs is not shown.
