Effects of Nitrogen-Doped Multiwall Carbon Nanotubes on Murine Fibroblasts

Figure 1

SEM micrographs of CN_x morphology and size distribution. Lengths were obtained from bundles of purified CN_x ((a), pointed with yellow arrows) and plotted to generate distribution patterns. Diameters were obtained from individual tubes from Helios SEM images (c) and distribution was plotted (d).
