Density-gradient ultracentrifugation can be used to separate empty (end-capped) and water-filled (open) carbon nanotubes, which coexist in aqueous solutions. As S. Cambré and W. Wenseleers report in their Communication on page 2764 ff., each nanotube chirality can be observed at two different densities, which correspond to empty and water-filled tubes. The separated empty and filled tubes can be further diameter-sorted in one centrifugation run.
