A macroscopic quantity of quasi‐spherical fullerene‐like shells (see Figure) that encapsulate iron nanoparticles containing radioisotope 99m Tc are prepared for the first time. The nanocomposite is acid‐non‐leachable, retaining radioactivity at an extremely high level. This method will enable rigorous studies of what are currently theoretical descriptions of nanometer‐scale medicinal delivery vehicles for diagnostic and therapeutic purposes.
