Endohedral metallofullerenes (M@C_2n) are carbon clusters that contain atoms trapped within a fullerene cage. This “atomic park“ of the 21 st century counts approximately 30 elements, mainly of the 2 nd group (Ca, Ba, Sr) and of the 3 rd group (Sc, Y, Ln) [1]. Some of them are paramagnetic and hold much promise for a variety of applications. For example, while Gd(III)-DTPA compounds are in current clinical use as contrast agents for magnetic-resonance imaging, the water proton relaxivity of Gd@C_ 82(OH)_n has turned out to be 20 times higher than that of the commercial contrast agent, Gd-DTPA [2]. M@C_ 2n with the appropriate particle-emitting radionuclide inside, like beta-emitting 89Sr, 90Y, 47Sc, 64Cu, 149Pr, 153Sm, 166Ho, and 177Lu, can be synthesized while advances in the molecular biotechnology provide targeting vectors to deliver therapeutic doses of the ionizing radiation with high specificity for treatment of metastasis cancer tumor cells [3]. There is an idea of utility of M@C_ 2n in the fullerene-based quantum computers [4]. A method for dividing a semiconductor nanotube into multiple quantum dots with lengths of about 10 nm for nanoelectronics by inserting Gd@C_ 82 in the metallofullerene peapods was reported [5].
