Nanotube chemistry. Computer model of a caged ion (blue) inside a carbon nanotube (green). The atoms of carbon (spheres) are linked to form hexagons (6-sided rings) that are joined to form the tube structure seen reflected in the ion. This tubular structure is an example of carbon nanochemistry, and is possible due to the unique chemistry of carbon. Structures like this, on the scale of a few atoms (the nanoscale), could be built and used for various applications. The caged ion could be part of a sensitive sensor system, or the size of the nanotube could be designed to filter ions of a certain size.
