One-dimensional heterostructure: The selective decoration of single-walled carbon nanotube tins with metallic nanoparticles

A straightforward protocol is presented to covalently bond gold nanoparticles exclusively at the tips of single-walled carbon nanotubes. This approach exploits the sterical hindrance given by a polymer and surfactant, preventing the attachment of no functionalized gold nanoparticles onto the main nanotube body. These novel heterostructures have promising potential for applications in photonics and electronic devices.
