^(a) estimate from neutron scattering experiments [45]; ^(b) maximum size corresponding to fully extended conformation (6 covalent bonds of 0.15 nm giving δ ≈ 1 nm); ^(c) h = 2R_G (mushroom regime, R_G is the radius of gyration of the PEG molecule in solution); ^(d) h = d_DLS-d_TEM (with d_DLS and d_TEM—average diameters measured by DLS and TEM, respectively); ^(e) brush regime, evaluation by Lin and Gast [46], Equation (2).
