      abstract     = {Nanoparticles with a multi-domain structure have been
                      identified as a new class of highly potent nanocarriers with
                      a dual transport mechanism for polar and non-polar guests.
                      In this paper we present a detailed analysis of their
                      spatial structure, which has been analyzed by small-angle
                      neutron scattering (SANS) including contrast variation. The
                      nanocarriers consist of a hyperbranched polyglycerol (hPG)
                      core onto which di-block segments consisting of non-polar
                      alkyl chains and hydrophilic poly(ethylene glycol) methyl
                      ether (mPEG) has been grafted. The hPG cores have been
                      analyzed separately for comparison. SANS demonstrates that
                      the hPG-cores can be described as fractal structures. The
                      nanocarriers form rather compact structures in the non-polar
                      solvent toluene. A fractal structure with a correspondingly
                      rough surface is found here as well, which is explained by
                      the backfolding of the hydrophilic mPEG-chains in the
                      non-polar environment. In water the nanocarriers associate
                      to form well-defined nanoparticle clusters with an
                      ellipsoidal shape. Contrast variation demonstrates that
                      these particles have no distinct core–shell structure but
                      the separation of the incompatible parts of the structure
                      takes place on a much smaller length scale.},
