From The Guardian:

The findings from animal research suggest workers involved in the manufacture of the materials may be at risk

Inhaling carbon nanotubes can suppress the immune system, according to scientists. The findings raise possible health concerns for those working in the manufacture of the materials.

Carbon nanotubes are rolled-up sheets of graphite thousands of times thinner than a human hair. Because they are immensely strong and are good electric conductors, they are poised for use in a wide range of fields from engineering to medicine. However, there are concerns over the similar shape of nanotubes and asbestos fibres, which are known to cause damage to the lungs in conditions such as mesothelioma.
