AFM image of 2D portion of Opened terminus of a uniform width, 1D nanoribbin generated using single unit cross-tile. The ribbon is formed by the flattening of a cylindrical tube on a mica surface. Nanoribbin continues 10 microns to the right. Image dimension: 500 nm x 500 nm.
AFM image of 6 TAO tiles assembled on a scaffold strand.
