volume of only 0.13 cubic nm, which is capable of holding a single
metal ion such as caesium.
Smaller cages have been made in the past, such as cubane (0.16nm
wide), but the new development is the first that can actually hold a
solid entity within, and is also one of the few that is not part of a
Possible applications include molecular detectors, the separation of
mixed solids, and even mopping up unwanted contaminants disolved in a
