AFM tapping mode topographic images of SWNT arrays. (A) Parallel aligned SWNTs with a line density approaching 5.0 × 107/cm2. (B) Linked SWNTs following MHA lines (20 μm × 200 nm) spaced by 2 μm, 1 μm, and 600 nm. (C) Random line structure, showing the precise positioning, bending, and linking of SWNTs to a MHA affinity template. All images were taken at a scan rate of 0.5 Hz. The height scale is 20 nm.
