“…5(a2), the CNT wall was magnified 50 times and lattice fringe is in parallel with the wire axis. The lattice spacing was measured to be 0.344 nm, which is in good agreement with the lattice spacing of CNT reported by Ke et al [33]. Fig.…”

“…S6, Electronic Supplementary Material). The SEM images of the artefacts caused by insufficient ion milling of the CNTs looks similar to the SEM images by Ke et al showing CNTs protruding from a surface [30]. To investigate whether it was in fact protruding CNTs, the sample was rotated to image the milled surface (almost) from the point of view of the ion beam (Fig.…”

Ultrastructural characterisation is important for understanding carbon nanotube (CNT) toxicity and how the CNTs interact with cells and tissues. The standard method for this involves using transmission electron microscopy (TEM). However, in particular, the sample preparation, using a microtome to cut thin sample sections for TEM, can be challenging for investigation of regions with agglomerations of large and stiff CNTs because the CNTs cut with difficulty. As a consequence, the sectioning diamond knife may be damaged and the uncut CNTs are left protruding from the embedded block surface excluding them from TEM analysis. To provide an alternative to ultramicrotomy and subsequent TEM imaging, we studied focused ion beam scanning electron microscopy (FIB-SEM) of CNTs in the lungs of mice, and we evaluated the applicability of the method compared to TEM. FIB-SEM can provide serial section volume imaging not easily obtained with TEM, but it is time-consuming to locate CNTs in the tissue. We demonstrate that protruding CNTs after ultramicrotomy can be used to locate the region of interest, and we present FIB-SEM images of CNTs in lung tissue. FIB-SEM imaging was applied to lung tissue from mice which had been intratracheally instilled with two different multiwalled CNTs; one being short and thin, and the other longer and thicker. FIB-SEM was found to be most suitable for detection of the large CNTs (Ø ca. 70 nm), and to be well suited for studying CNT agglomerates in biological samples which is challenging using standard TEM techniques.Figure3D FIB-SEM image reconstruction of carbon nanotube (CNT) sample in lung tissue obtained with the double tilted milling method. A few CNTs have manually been traced in the 3D volume, and the white arrowheads point to a single CNT.

“…Different electrontransparent lamellas were prepared by following a similar procedure described elsewhere. 44 In-plane conductivity of the samples was carried out by the four-probe Van der Pauw method by using silver-gold ink and Au wires for the electrical connections. The measurements were carried out in synthetic air between room temperature and 600 °C, during the heating and cooling cycles to test the reproducibility of the data.…”
