Fig. 3.
Optical microscopy images of BEAS-2B cells exposed to SWCNTs with different physicochemical properties, namely pristine (B), 3 (C) or 6 h (D), all relative to controls (A). Fluorescent images in Panel 1 show changes in the confluence level and their dependency on the SWCNTs physicochemical properties. Panel 2 shows bright field images of the exposed cells, and reveals nanotubes localization at the nucleus or perinuclear region. Panel 3 identified changed nuclear morphologies as resulted upon exposure to user-tailored SWCNTs (arrows).
