Abstract

Well-defined length fractions of DNA-wrapped single-walled carbon nanotubes (SWNTs) of below 200 nm are taken up preferentially by IMR-90 human lung fibroblasts, while longer DNA wrapped SWNTs are excluded from the cell interior (inset), report Matt Becker and coworkers on p. 939. The cover image construct includes overlaid images of the labeled cell membrane, the nuclei (blue), and the fluorescently labeled DNA wrapped SWNTs (red) that have gained access to the cell interior.
