  1. Hydrodynamic radius in water, Rh, radius from SANS in D2O, RSANS = RSANS,c + 2σSANS where RSANS,c is the core radius in bulk and 2σSANS is the fuzziness of the shell in bulk determined by SANS. 2R2D is the interfacial (dry) diameter and 2R2D,c is the interfacial (dry) diameter of the core. h2D is the maximum height once adsorbed (dry). The last three quantities are determined by AFM, see Supplementary Figs. 3 and 4. The values including the errors are given in Supplementary Table 1.
