| 1. A method for the production of a dispersed, carbon Nanotube—nucleic acid complex comprising:
a) providing a stabilized solution of single stranded nucleic acid molecules;
b) contacting a population of unfunctionalized, single walled carbon nanotubes with an effective amount of the stabilized
nucleic acid solution of step (a) for a time sufficient for the single stranded nucleic acid molecules to associate with the
carbon nanotubes by non-covalent means to form a dispersed, carbon nanotube—nucleic acid complex; and
c) optionally recovering the dispersed, carbon nanotube—nucleic acid complex.
