After the gold-NP chains had been formed, the removal of NaCl by using ionic-exchange resin - thereby increasing the electrostatic repulsion - did not disaggregate them;instead , it enhanced their colloidal stability and the electron coupling between them (see the Supporting Information). We therefore conclude that when the NPs self-assemble into a chain, their electrostatic double layers are rearranged to build a uniform electrostatic double layer surrounding the entire NP chain.
