These structural parameters are the micelle core radius (R_s), solvophobic block volume (V_mc), overall particle diameter (D_total = R_s + 2R_g), mean aggregation number of copolymer chains per spherical micelle (N_agg), and the number of copolymer chains normalized with respect to the surface area of the spherical nanoparticles [S_agg = N_agg/(4πR_s²)]. Further details regarding these SAXS spherical micelle model parameters can be found in the Supporting Information.
