ABSTRACT:
The present invention relates to the use of a carbon nanotube comprising positive and/or negative charges, the charges being carried by at least one charge-carrying group, the charge carrying group being covalently bound to the surface of the carbon nanotube, for the manufacture of a complex between the carbon nanotube and at least one charged molecule, the bond between the carbon nanotube and the charged molecule being essentially electrostatic, and the charged molecule comprising at least one negative charge if the carbon nanotube comprises positive charges and/or at least one positive charge if the carbon nanotube comprises negative charges.
