Rat neuronal cultures on CNT islands. (A) Fluorescent confocal image of fixed neurons (red) and glia cells (green) cultured on a carbon nanotube island. Disk diameter is 20 μm. (B,C) HRSEM images of a neuronal process forming a loop around several CNTs (designated by arrows). The image in (C) corresponds to the area marked by the dashed box in (B). Clearly identifiable process segments were manually highlighted. Processes appear to bind to the carbon nanotube surface in a manner akin to that of tendrils. Adopted from Sorkin et al. (2009).
