Carbon Nanotubes - Behaviour

Carbon nanotubes (CNT) can be taken up into the cells.

Very little has been known so far on the uptake of carbon nanotubes (CNT) from the blood into the brain passing the blood-brain barrier.

Although they consist only of a carbon skeleton, carbon nanotubes (CNTs) have a plurality of different structures: single-walled and multi-walled tubes, different lengths, and surface coatings. These variations make it difficult to directly compare the environmental behaviour of carbon nanotubes. They also are often not present as single tube, but are aggregated to bundles. Therefore it is difficult to generalise about the environmental fate of this great diversity of CNTs.
