Surface functionalization of single-walled carbon nanotubes (SWCNTs) was carried out using fuming nitric acid as a NO 2 radical source. The surface double bonds of the SWCNTs reacted with the NO 2 radicals at 10-90 Β°C under sonication, and following treatment with aqueous NaOH yielded modified carbo
**Singleβwalled carbon nanotube (SWNT) bundles** have been dispersed by an electrolysis method. Intercalation of bundles by NO~3~^β^ widens locally the interβtube spacing. Bundles are nanodispersed into individual nanotubes after deintercalation (see Figure). This method could be used to fabricate e
