In order to get a better understanding of the association mechanism that leads to the formation of DNA/single-walled carbon nanotube (SWNT) complexes, we solubilised and dispersed SWNTs in aqueous medium using single-stranded DNA with a poly (GT)15 sequence. Optical and microscopic characterizations of the complexes permits to confirm that the SWNTs were individualized or embedded in small bundles. The presence of these bundles excludes that helical wrapping may be the unique possible association mechanism.
