Hemolytic Effects of Water-Soluble Fullerene Derivatives
摘要:
A series of water-soluble fullerene C-60 derivatives has been investigated for their cytotoxic and hemolytic properties, with the aim to correlate structure with toxicity. We observed that cationic chains induce significant toxicity while the presence of neutral or anionic moieties did not produce any response in our model. A validation of these experimental observations has been performed by theoretical studies in which hydrophilic and hydrophobic surface areas were correlated quantitatively with hemolytic properties.

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.
