Linear Assemblies of Silica-Coated Gold Nanoparticles Using Carbon Nanotubes as Templates


  • Prof. K. Kempa and Prof. Z. Ren from Boston College and Nanolab Inc. are acknowledged for supplying both powdered and aligned MWNT samples.


Silica-coated gold nanoparticles were assembled on carbon nanotubes by polymer wrapping and layer-by-layer assembly (see Figure). The procedure was applied to ordered arrays of vertically aligned nanotubes, resulting in parallel nanotubes of compact nanoparticle monolayers for potential use in photonics.
