… can be used to separate empty (end-capped) and water-filled (open) carbon
nanotubes, which coexist in aqueous solutions. As S. Cambr 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.
