'Cloaked' carbon nanotubes become non-toxic

A way to cloak carbon nanotubes, making them both non-toxic and highly customisable, has been revealed. It marks a step towards using nanotubes in biological research and medicine.

Nanotubes are rolled up sheets of linked carbon atoms and are as little as 10 atoms wide. In the future they could act as tiny molecular sensors, detecting individual enzymes inside living cells, or could enable new medical treatments for diseases such as cancer (...)
