Cells Selectively Absorb Short Nanotubes (IMAGE)
Caption
Nanotube length threshold: NIST experiments using human lung cells demonstrate that DNA-wrapped single-walled carbon nanotubes longer than about 200 nanometers are excluded from cells, while shorter lengths are able to penetrate the cell interior (dark lines in the fluorescence image above).
