HRTEM images of t-ox-MWCNTs in the tissue at 2 years after implantation.

(a) HRTEM image of t-ox-MWCNTs in the intercellular space. (b) Low-magnification HRTEM image of t-ox-MWCNTs in the macrophage. (c) High-magnification HRTEM image of t-ox-MWCNTs in the macrophage. (d) HRTEM image of a 3–5 nm thick layer (white arrows) on the surface of a t-ox-MWCNT. (e) HRTEM image of t-ox-MWCNTs in a secondary lysosome in a macrophage. (f) High-magnification HRTEM image of the image shown in panel (e). The lattice images of the outer layers of MWCNTs are not clearly defined (white arrows). The insets in panels (a), (c) and (f) are high-magnification images of the boxed areas indicated. The scale bar in all insets is 5 nm. The HRTEM images are representative of greater than 100 independent observation areas in each implanted t-ox-MWCNT.
