One-dimensional Au nanoparticles connected by ionic linkers self-assemble into a micrometer-scale network. Reactions between linker ions reinforce the assembly and lead to the formation of a continuous network. This continuous network demonstrates room-temperature Coulomb-blockade characteristics that are indicative of electron transport along the 1D pathways.
