DNA nanostructures based on tile assembly. a Seeman’s proposal about utilization of branched DNA motifs to create 3D scaffold for protein crystallization [105]. b Examples of 2D arrays assembled by DX tile (left) [108], three-point-star tile (middle) [115], and three-helix bundle (right) [112]. c Examples of DNA assembled cube (left) [120], tetrahedron (middle) [121], and dodecahedron (right) [122]. d 3D DNA crystals formed by tensegrity triangle (top) [123], and six-symmetry motif (bottom) [127].
