Abstract

Nitrogen-containing carbon nanotube cups are crosslinked with glutaraldehyde to form capsule-shaped nanostructures. Introduction of commercially available gold nanoparticles prior to the crosslinkage process results in their encapsulation within the interior cavity of the linked structures (see image). A similar encapsulation of ZnS:Tb nanoparticles shows the general applicability of the system. Such a facile protocol alludes to drug-delivery and energy-storage applications.
