WebFullerene is a molecule of Carbon. The shape of the molecule can be in the form of a hollow sphere, ellipsoid, tube, and many other shapes. The first fullerene molecule was produced in 1985 by these scientists; Richard Smalley, Robert Curl, James Heath, Sean O'Brien and Harold Kroto at Rice University. 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.
