First Direct Images of Carbon Nanotubes Entering Cells

For the first time, scientists have directly imaged carbon nanotubes entering and migrating within human cells, determining as a result that whether the nanotubes cause cell death depends on the dose and exposure time. The work, published in the October 28 online edition of Nature Nanotechnology, may lead to better ways of determining carbon nanotubes' toxicity to humans.
