(a) An AFM image of a single-layer rectangular origami structure as in literature1. (b) A TEM image of a multilayer three-dimensional origami structure. (c) A small scaffold-free three-dimensional ‘DNA-brick’5 structure. Scale bars in a,b, 100 nm; in c, 50 nm. Panel a was folded with oligonucleotides from Fig. 3 lane 6; b with Fig. 3 lane 4.
