Selective attachment of functionalized nanospheres to carbon nanotubes-distributed template in a large area

An effective 3-D nanostructure for nano-sized devices was designed using single-walled carbon nanotubes (SWNTs) as a main frame of the structure. The -NH2 modified polystyrene (PS) nanosphere with an average diameter of 100 nm could form SWNT-PS nanosphere composite and selective attachment to SWNT distributed on gold template by covalent combination, which were accomplished by using two different processes. These results may enable carbon nanotubes to be applied to the construction of nanostructures.
