Upper panel (a–c) [23]: (a) schematic of a 4 × 4 tile and nanoribbon assembly form from these tiles; (b) AFM image of a nanoribbon; (c) SEM image of a metallized silver nanoribbon, scale bar 500 nm; middle panel (d–g) [87]: (d) scheme of a nanotube made of TX tiles; (e,f) TEM and SEM image of nanotubes; (g) SEM image of a metallized silver nanotube; scale bars in (e–g) are 100 nm, 1 μm and 1 μm, respectively; lower panel (h–j) [24]: (h) assembly model of a nanotube from a single oligonucleotide with palindromic sequence, (i) AFM image of the nanotube; (j) metallized Pd nanotube.
