Water-soluble carbon nanotube compositions for drug delivery and medicinal applications

A composition comprising:

• a plurality of functionalized single-wall carbon nanotubes;
• wherein the functionalized single-wall carbon nanotubes are water-soluble;
• and
• wherein the functionalized single-wall carbon nanotubes are covalently functionalized with a plurality of PEG moieties;
• and
• a drug molecule comprising paclitaxel;
• wherein the paclitaxel is insoluble in water;
• wherein the paclitaxel is non-covalently associated with the functionalized single-wall carbon nanotubes;
• and
• wherein the paclitaxel is sequestered from its surrounding environment by the non-covalent association with the functionalized single-wall carbon nanotubes.
