Assembly of single-walled carbon nanotubes on patterns of Au nanoparticles

► Assembly and alignment of single-walled carbon nanotubes (SWNTs) on micron scale patterns of Au nanoparticles (NPs). ► Extensive adhesion and strong affinity of SWNTs on the Au NPs and no SWNT on ODT was observed. ► Partial coverage of ODT with Au does not allow the CNTs to assemble until ODT is almost covered with Au particles/clusters. ► DCA measurements revealed a direct correlation between the surface wettability and the SWNTs assembly on a molecular template.
