WebFullerenes are a class of inorganic carriers, these molecules are preferred as they show good bio compatibility, greater selectivity, retain the biological activity, and are small enough to be diffused. DNA sequences are attached to the amino acid derivatives of fullerene. WebFullerene is the molecule of carbon atoms with fused pentagons and hexagons forming hollow structures of the sphere, ellipsoid, tube, and many other shapes. Buckminsterfullerene C60 was the first fullerene molecule to be discovered in 1985, and is made of 60 carbon atoms in the shape of a hollow sphere.
