Functionalized carbon nanotubes are taken up by cells via a possible universal mechanism
Michael Freemantle

The uptake of functionalized carbon nanotubes by living cells does not depend on cell type or on the nature of the chemical moieties grafted onto the tubes, according to a new study (Nat. Nanotechnol., DOI: 10.1038/nnano.2006.209). The research also provides evidence that nanotubes act like nanoneedles when they penetrate cell membranes.
