The radial density distributions of the terminal groups (top) and the absolute value of the ionic charge density distributions (bottom). For MUS− and MPS− ligands, only the sulfonate S-atom of the terminal group was selected; and for the pMBA− and pMBM+ ligands, only the farthest carbon atom from the NP surface was selected. In the SI is presented the density distributions of the terminal groups, and the Na+ and Cl− ions for each system separately (ESI, Figs. S4-S5). The peak position of the terminal-group distribution (top) is approximately equal to the radius of the AuNP as a whole (core plus ligands).
