Construction, DNA wrapping and cleavage of a carbon nanotube-polypseudorotaxane conjugate.
A supramolecular assembly of carbon nanotubes was constructed by non-covalently wrapping cyclodextrin-based polypseudorotaxanes on single wall carbon nanotubes; the assembly showed good abilities in wrapping and cleaving double-stranded DNA.
