a Apparent weight-average molecular weight estimated from static light scattering (SLS). b Aggregation number of PICsomes calculated by dividing Mw(SLS) with that of unimers. c Radius of gyration estimated from SLS. d Hydrodynamic radius estimated from dynamic light scattering (DLS). e Second virial coefficient estimated from SLS. f Refractive index increment. g Density of polymers and PICsomes calculated from Equation (5). h PICsome composed of P20M190 and P20A196 with f+ = 0.5.
