DNA double crossover (DX) motifs including DAE (double crossover, antiparallel, even spacing) and DAO (double crossover, antiparallel, odd spacing) are well-known monolayered DNA building blocks for construction of 2D DNA arrays and tubes in nanoscale and microscale. Compared to the 3D architectures of DNA origami and single-stranded DNA bricks to build nanoscale 3D bundles, tessellations, gears, castles, etc., designs of double- and multi-layers of DX motifs for 3D architectures are still limited. Herein, we report two types of double-layered tiles derived from DAE motifs with single-stranded circular 42- and 64-nt oligonucleotides as scaffold strands. Further tiling of the tiles generated planar 3D crystalline domains and curved tubes, correspondingly. Finally, we applied the chiral index theory to derive the unit tube parameters of six E-tiling (inter-tile distance of even spacing) tubes and analyzed the causation of difference between these tubes.
