When a mixed self-assembled monolayer forms on the curved surface of a gold nanoparticle two opposed point defects must form for topological reasons. Here we present a thermodynamic study proving that these defects are more reactive than other sites on the nanoparticle, and demonstrate that the energy of the reaction depends on the ligand molecules.
