Metallic nitride clusters entrapped within fullerene cages have sparked an array of multidisciplinary research. In particular, these metallic nitride fullerenes (MNFs) are of interest to medical applications. However, these investigations are hampered by a lack of sample availability. This is due in part by limitations of current chromatographic approaches. Herein, we report a scalable, non-chromatographic method using amino functionalized silica gel to selectively remove contaminant fullerenes (e.g. C60, C70). Results indicate purity levels of MNFs at >99%.
