Abstract
2D Archimedean tiling and complex tessellation patterns assembled from soft materials including modular DNA tiles have attracted great interest because of their specific structures and potential applications in nanofabrication, nanoelectronics, nanophotonics, biomedical sensing, drug delivery, therapeutics, etc. Traditional three- and four-point-star DNA tiles with the core arm length at two half-turns (specified as three- and four-point-star-E previously and abbreviated as 3PSE and 4PSE tiles here) have been applied to assemble intricate tessellations through tuning the size of inserted nT (n = 1-7, T is thymine) loops on helper strands at the tile center. Following our recent findings using a new type of four-point-star tiles with the core arm length at three half-turns (specified as four-point-star-O previously and abbreviated as 4PSO tiles here) to assemble DNA tubes and flat 2D arrays, we report here the cross-hybridization weaving architectures at the tile center to construct three new 3PSO tiles with circular DNA oligonucleotides of 96-nt (nucleotides) serving as the scaffolds, further the monotonous and combinatory E- and O-tilings on one type of 3PSO tiles to create 2D Archimedean tiling patterns (6.6.6) and (4.8.8), and finally, the combination of 3PSO with 4PSO as well as 2PSO tiles to tile into complex tessellation patterns. The easy realization of regular and intricate DNA tessellations with 2-4PSO tiles not only richens the fundamental DNA modules and complex DNA nanostructures in types but also broadens the potential application scopes of DNA nanostructures in nanofabrication, DNA computing, biomedicine, etc.

Abstract
In structural DNA nanotechnology, E-tiling DNA nanotubes are evidenced to be homogeneous in diameter and thus have great potential in biomedical applications such as cellular transport and communication, transmembrane ion/molecule channeling, and drug delivery. However, a precise structural description of chiral DNA nanotubes with chiral parameters was lacking, thus greatly hindering their application breadth and depth, until we recently raised and partly solved this problem. In this perspective, we summarize recent progress in defining the chiral indices and handedness of E-tiling DNA nanotubes by microscopic imaging, especially atomic force microscopy (AFM) imaging. Such a detailed understanding of the chiral structures of E-tiling DNA nanotubes will be very helpful in the future, on the one hand for engineering DNA nanostructures precisely, and, on the other, for realizing specific physicochemical properties and biological functions successfully.

Abstract
Using oligonucleotides to weave 2D tiles such as double crossovers (DX) and multi-arm junction (mAJ) tiles and arrays is well-known, but weaving 3D tiles is rare. Here, we report the construction of two new bilayer tiles in high yield using small circular 84mer oligonucleotides as scaffolds. Further, we designed five E-tiling approaches to construct porous nanotubes of microns long in medium yield via solution assembly and densely covered planar microscale arrays via surface-mediated assembly.

Abstract
By rationally adjusting the weaving modes of point-star tiles, the curvature inherent in the tiles can be changed, and various DNA nanostructures can be assembled, such as planar wireframe meshes, perforated wireframe tubes, and curved wireframe polyhedra. Based on the weaving and tiling architectures for traditional point-star tiles with the core arm length at two DNA half-turns, we improved the weaving modes of our newly reported four-point-star tiles with the core arm length at three half-turns to adjust their curvature and rigidity for assembling 2D arrays of DNA grids and tubes. Following our previous terms and methods to analyze the structural details of E-tiling tubes, we used the chiral indices (n,m) to describe the most abundant tube of typical assemblies; especially, we applied both one-locus and/or dual-locus biotin/streptavidin (SA) labelling strategies to define the configurations of two specific tubes, along with the absolute conformations of their component tiles. Such structural details of the DNA tubes composed of tiles with addressable concave and convex faces and packing directions should help us understand their physio-chemical and biological properties, and therefore promote their applications in drug delivery, biocatalysis, biomedicine, etc.

Abstract
The overwinding and underwinding of DNA duplexes between junctions have been used in designing left- and right-handed DNA origami nanostructures, respectively. For DNA tubes obtained from self-assembled tiles, only a theoretical approach of the intrinsic curvature of the tiles has been previously used to explain their formation. Details regarding the quantitative and structural descriptions of the tile's intrinsic curvature in DNA nanostructures have so far never been addressed. In this work, we designed three types of tile cores built around a circular scaffold using three- and four-branched junctions. Joining the tile cores with arms having two kinds of inter-tile distances, an odd and an even number of DNA half-turns, tended to form planar 2D lattices and tubes, respectively. Streptavidin bound to biotin was used as a labeling technique to characterize the inside and outside surfaces of the tubes and thereby the tile conformation of dihedrals with addressable faces. DNA tubes with either right- or left-handed chirality were obtained by the coupling of the intrinsic curvature of the tiles with the arm twist. We were able to assign the chiral indices (n,m) to a tube with its structure resolved by AFM at the single-tile level and therefore to estimate the global curvature of the tube (or its component tile) using a regular polygon model that approximated its transverse section. A deeper understanding of the integrated actions of different types of twisting forces on DNA tubes will be extremely helpful in engineering more elaborate DNA nanostructures in the future.

Abstract
Cyclic rings of single-stranded (ss) DNA have various unique properties, but wider applications have been hampered by their poor availability. This paper reports a convenient one-pot method in which these rings are efficiently synthesized by using T4 DNA ligase through convergent cyclization of easily available short DNA fragments. The key to the present method is to separate all the splint oligonucleotides into several sets, and add each set sequentially at an appropriate interval to the solutions containing all the short DNA fragments. Compared with simple one-pot strategies involving simultaneous addition of all the splints at the beginning of the reaction, both the selectivity and the yields of target ssDNA rings are greatly improved. This convergent method is especially useful for preparing large-sized rings that are otherwise hard to obtain. By starting from six short DNA fragments (71-82 nt), prepared by a DNA synthesizer, a ssDNA ring of 452-nt size was synthesized in 35 mol % yield and in high selectivity. Satisfactorily pure DNA rings were obtainable simply by treating the crude products with exonuclease.

Abstract
One-layer multi-arm junction (mAJ) motifs have been investigated extensively for many kinds of planar 2D (two-dimension) lattices, surface-curved 3D (three-dimension) polyhedra, and complex 3D wireframe and tensegrity structures. Herein, we report the weaving strategy to achieve two-layer stacked multi-arm junction tiles (abbreviated as mAJ2) of 3AJ2 and 4AJ2, and several primary tessellation nanostructures of nanocages and 2D rhombus lattices carrying beautifully embossed 4-point stars. Challenges for perfect tessellation are also raised regarding the increase of motif complexity from 2D to 3D.

Abstract
Camptothecin (CMPT) in a free form is extremely cytotoxic as well as hydrophobic drug, and is considered to be highly contagious for systemic administration. The fibronectin (FN)-functionalized DNA-based nanocarrier has been designed to load CMPT and target integrin (αvβ3) receptors which are highly expressed on the A549 cancer cells. Here, we report DNA nanocarrier in the form of DNA-nanofibers (DNA-NFs) capable of loading CMPT via strand intercalation in the GC (base pairs)-rich regions of the DNA duplex. Hence, our keen purpose was to explore the potential of DNA-NFs to load CMPT and assess the improvements of the outcomes in terms of enhanced therapeutic effects to integrin-rich A549 cancer cells with reduced cytotoxic effects to integrin-lacking HEK293 cells. DNA-NFs were formulated as a polymer of DNA triangles. DNA triangles arranged in a programmed way through the complementary overhangs present at the vertices. DNA triangles were primarily obtained through the annealing of the freshly circularized scaffold strands with the three distinct staple strands of specific sequences. The polymerized triangular tiles instead of forming two-dimensional nanosheets underwent self-coiling to give rise to DNA-NF-shaped structures. Flow cytometry and MTT assays were performed to observe cytotoxic and apoptotic effects on integrin-rich A549 cancer cells compared with the integrin-deficient HEK293 cells. AFM, native-page, and confocal experiments confirmed the polymerization of DNA triangles and the morphology of the resulting nanostructures. AFM and confocal images revealed the length of DNA-NFs to be 3-6 μm and the width from 70 to 110 nm. CMPT loading (via strands intercalation) in GC-rich regions of DNA-NFs and the FN functionalization (TAMRA tagged; red fluorescence) via amide chemistry using amino-modified strands of DNA-NFs were confirmed through the UV-shift analysis (> 10 nm shift) and confocal imaging. Blank DNA-NFs were found to be highly biocompatible in 2-640 μM concentrations. MTT assay and flow cytometry experiments revealed that CMPT-loaded DNA-NFs showed a dose-dependent decrease in the cell viability to integrin-rich A549 cancer cells compared with the integrin-deficient HEK293 cells. Conclusively, FN-functionalized, CMPT-loaded DNA-NFs effectively destroyed integrin-rich A549 cancer cells in a targeted manner compared with integrin-deficient HEK293 cells. Grapical abstract.

Abstract
Poly(A-T)-rich sequences have been applied as stems of DNA dumbbell tiles for construction of single crystalline 2D DNA lattice arrays in slightly acidic solutions. These arrays show much higher stability and better organised crystalline lattice structures than those assembled from DNA dumbbell tiles with randomly sequenced stems in slightly alkaline environments. DNA nanotechnology probably provides a useful platform to study the mechanical properties of DNA duplexes with specific sequences.
