Abstract

Dispersion of CNTs with single-strand (ss) and hairpin (hp) DNA yields suspensions with varying degree of individualization and selectivity towards specific tube types. Time-resolved fluorescence spectroscopy with dye labelled oligomers is used to investigate structural properties of DNA–SWNT conjugates. hpDNA is found to bind with its loop sideways to the CNT surface.
