Cells selectively absorb short nanotubes

DNA-wrapped single-walled carbon nanotubes (SWCNTs) shorter than about 200 nanometers readily enter into human lung cells and so may pose an increased risk to health, according to scientists at the National Institute of Standards and Technology. The results of their laboratory studies appear in an upcoming issue of Advanced Materials.
