简介
A length threshold for cell uptake of DNA‐wrapped single‐walled carbon nanotubes (SWNTs) by human lung fibroblasts (IMR90) is identified. Competitive uptake experiments with well‐defined and characterized length fractions show that SWNTs above the length threshold are excluded from the cell, whereas SWNTs labeled with Cy3‐derivatized DNA below the threshold are able to access the cell interior, as shown in the fluorescence image and on the cover.
