C 60 Fullerenes as Contrast Agents - Structural, Spectroscopic and Nanotoxicity Studies

Endohedal Fullerenes C 60 and C 82 with Silver

The models of endofullerenes C 60 and C 82 with silver atom or diatomic silver are calculated with ab initio SCF Hartree-Fock methods including the full geometry optimization. Ag@C 60 is a bound system with positive binding energy while Ag 2 @C 60 is not because strong geometrical strain. Silver atom is located at some distance from the cage center in the lower-energy model, and the structure r...

Fullerenes as Agents for Chemotherapeutic Drug Delivery

In a world where the scale of technology is continuously shrinking, from phones to cars to solar panels, nanotechnology is seeing a rise in applications. Recently, increased use of nanotechnology in the medical industry brought fullerenes, sometimes referred to as Buckyballs, to the forefront. Fullerenes are currently being developed by engineers to encapsulate a chemotherapeutic drug and deliv...

Fullerenes C 60 self - assembled on functionalized surfaces

Memory devices play an important role in electronics market leading to a growing research interest in the next generation of non-volatile memory cells. Numerous groups [1,2] work on top-down memory cells based on fullerenes C60 that are generally embedded in insulating polymers where they act as storage sites. Beside these studies, a reaction path between amines and fullerenes [3] may be used t...

Reactivity and regioselectivity of noble gas endohedral fullerenes Ng@C(60) and Ng(2)@C(60) (Ng=He-Xe).

Recently, it was shown that genuine Ng-Ng chemical bonds are present in the endohedral fullerenes Ng(2)@C(60) in the case of Ng=Xe, while it is more debatable whether a chemical bond exist for Ng=Ar and Kr. The lighter homologues with helium and neon are weakly bonded van der Waals complexes. The presence of a noble gas dimer inside the cage is expected to modify the exohedral reactivity of the...
