      abstract     = {The properties of ligand protected gold nanoparticles are
                      determined by the synergistic interplay of their structural
                      components, including the metal core, the ligand shell, and
                      the solvation layer. However, the simultaneous
                      characterization of all these components remains a major
                      challenge given their disparate chemical nature. In the case
                      of mixed ligand nanoparticles, this task becomes daunting
                      due to the presence of intercorrelated additional parameters
                      such as the ligand ratio, ligand spatial distribution, and
                      solvation of the heterogeneous ligand shell. Here we show
                      that small angle neutron scattering (SANS) is a tool capable
                      of simultaneously characterizing the core and the ligand
                      shell of monodisperse mixed ligand gold nanoparticles. We
                      systematically examine how each parameter (e.g., the core
                      size, the thickness, composition and the spatial
                      heterogeneity of the ligand shell) affects nanoparticles’
                      scattering profile. Quantitative information on these
                      parameters is retrieved using analytical fitting as well as
                      3D modeling. Importantly, we show that SANS can evaluate the
                      solvation degree of mixed ligand protected gold
                      nanoparticles, a challenging task for any other
                      characterization methods.},
