Water-solubilization of nucleotides-coated single-walled carbon nanotubes using a high-speed vibration milling technique.

[reaction: see text] Pristine single-walled carbon nanotubes (SWNTs) and nucleotides mixed using a mechanochemical high-speed vibration milling technique (HSVM) are soluble in an aqueous solution, and the solubilities of SWNTs depend significantly on the number of phosphate groups and the kinds of bases employed.
