[60] Fullerene has been nanoencapsulated by the formation of an inclusion complex with a beta-cyclodextrin-containing lactose copolymer. The cyclodextrin polymer was synthesized by reaction of beta-cyclodextrin chlorotriazine with beta-lactose, and the polymer was highly soluble in water. Encapsulation of the carbon allotrope was achieved by forming a stable inclusion complex between the water-soluble cyclodextrin and [60] fullerene by a new synthetic procedure. Preliminary studies indicate that this complex has potential for biomedical applications because of its radical scavenging properties.
