Abstract
Controlling the three-dimensional (3D) nanoarchitecture of inorganic materials is imperative for enabling their novel mechanical, optical, and electronic properties. Here, by exploiting DNA-programmable assembly, we establish a general approach for realizing designed 3D ordered inorganic frameworks. Through inorganic templating of DNA frameworks by liquid- and vapor-phase infiltrations, we demonstrate successful nanofabrication of diverse classes of inorganic frameworks from metal, metal oxide and semiconductor materials, as well as their combinations, including zinc, aluminum, copper, molybdenum, tungsten, indium, tin, and platinum, and composites such as aluminum-doped zinc oxide, indium tin oxide, and platinum/aluminum-doped zinc oxide. The open 3D frameworks have features on the order of nanometers with architecture prescribed by the DNA frames and self-assembled lattice. Structural and spectroscopic studies reveal the composition and organization of diverse inorganic frameworks, as well as the optoelectronic properties of selected materials. The work paves the road toward establishing a 3D nanoscale lithography.

Abstract
Here, we study optically resonant substrates fabricated using the previously reported BLIN (biotemplated lithography of inorganic nanostructures) technique with single triangle and bowtie DNA origami as templates. We present the first optical characterization of BLIN-fabricated origami-shaped silver nanoparticle patterns on glass surfaces, comprising optical transmission measurements and surface-enhanced Raman spectroscopy. The formed nanoparticle patterns are examined by optical transmission measurements and used for surface enhanced Raman spectroscopy (SERS) of Rhodamine 6G (R6G) dye molecules. Polarization-resolved simulations reveal that the higher SERS enhancement observed for the bowties is primarily due to spectral overlap of the optical resonances with the Raman transitions of R6G. The results manifest the applicability of the BLIN method and substantiate its potential in parallel and high-throughput substrate manufacturing with engineered optical properties. While the results demonstrate the crucial role of the formed nanogaps for SERS, the DNA origami may enable even more complex nanopatterns for various optical applications.

Abstract
Molecular recognition-driven self-assembly employing single-stranded DNA (ssDNA) as a template is a promising approach to access complex architectures from simple building blocks. Oligonucleotide-based nanotechnology and soft-materials benefit from the high information storage density, self-correction, and memory function of DNA. Here we control these beneficial properties with light in a photoresponsive biohybrid hydrogel, adding an extra level of function to the system. An ssDNA template was combined with a complementary photo-responsive unit to reversibly switch between various functional states of the supramolecular assembly using a combination of light and heat. We studied the structural response of the hydrogel at both the microscopic and macroscopic scale using a combination of UV-vis absorption and CD spectroscopy, as well as fluorescence, transmission electron, and atomic force microscopy. The hydrogels grown from these supramolecular self-assembly systems show remarkable shape-memory properties and imprinting shape-behavior while the macroscopic shape of the materials obtained can be further manipulated by irradiation.

Abstract
We studied the directed self-assembly of two types of complementary single-stranded DNA (ssDNA) strands [i.e., poly(dA) and poly(dT)] into more complex, organized, and percolating networks in dilute solutions and at surfaces. Understanding ssDNA self-assembly into 2D networks on surfaces is important for the use of such networks in the fabrication of well-defined nanotechnological devices, as, for instance, required in nanoelectronics or for biosensing. To control the formation of 2D networks on surfaces, it is important to know whether DNA assemblies are formed already in dilute solutions or only during the drying/immobilization process at the surface, where the concentration automatically increases. Fluorescence cross-correlation spectroscopy clearly shows the presence of larger DNA complexes in mixed poly(dA) and poly(dT) solutions already at very low DNA concentrations (<1 nM), that is, well below the overlap concentration. Here, we describe for the first time such supramolecular complexes in solution and how their structure depends on the ssDNA length and concentration and ionic strength. Hence, future attempts to control such networks should also focus on network precursors in solution and not only on their immobilization on surfaces.

Abstract
The one-atom-thick graphene has excellent electronic, optical, thermal, and mechanical properties. Currently, chemical vapor deposition (CVD) graphene has received a great deal of attention because it provides access to large-area and uniform films with high-quality. This allows the fabrication of graphene based-electronics, sensors, photonics, and optoelectronics for practical applications. Zero bandgap, however, limits the application of a graphene film as electronic transistor. The most commonly used bottom-up approaches have achieved efficient tuning of the electronic bandgap by customizing well-defined graphene nanostructures. The postgrowth transfer of graphene films/nanostructures to a certain substrate is crucial in utilizing graphene in applicable devices. In this review, the basic growth mechanism of CVD graphene is first introduced. Then, recent advances in various transfer methods of as-grown graphene to target substrates are presented. The fabrication and transfer methods of graphene nanostructures are also provided, and then the transfer-related applications are summarized. At last, the challenging issues and the potential transfer-free approaches are discussed.

Abstract
The surface-assisted hierarchical assembly of DNA origami nanostructures is a promising route to fabricate regular nanoscale lattices. In this work, the scalability of this approach is explored and the formation of a homogeneous polycrystalline DNA origami lattice at the mica-electrolyte interface over a total surface area of 18.75 cm2 is demonstrated. The topological analysis of more than 50 individual AFM images recorded at random locations over the sample surface showed only minuscule and random variations in the quality and order of the assembled lattice. The analysis of more than 450 fluorescence microscopy images of a quantum dot-decorated DNA origami lattice further revealed a very homogeneous surface coverage over cm2 areas with only minor boundary effects at the substrate edges. At total DNA costs of € 0.12 per cm2 , this large-scale nanopatterning technique holds great promise for the fabrication of functional surfaces.

Abstract
Viruses are among the most intriguing nanostructures found in nature. Their atomically precise shapes and unique biological properties, especially in protecting and transferring genetic information, have enabled a plethora of biomedical applications. On the other hand, structural DNA nanotechnology has recently emerged as a highly useful tool to create programmable nanoscale structures. They can be extended to user defined devices to exhibit a wide range of static, as well as dynamic functions. In this review, we feature the recent development of virus-DNA hybrid materials. Such structures exhibit the best features of both worlds by combining the biological properties of viruses with the highly controlled assembly properties of DNA. We present how the DNA shapes can act as "structured" genomic material and direct the formation of virus capsid proteins or be encapsulated inside symmetrical capsids. Tobacco mosaic virus-DNA hybrids are discussed as the examples of dynamic systems and directed formation of conjugates. Finally, we highlight virus-mimicking approaches based on lipid- and protein-coated DNA structures that may elicit enhanced stability, immunocompatibility and delivery properties. This development also paves the way for DNA-based vaccines as the programmable nano-objects can be used for controlling immune cell activation.

Abstract
The surface-assisted hierarchical assembly of DNA nanostructures into regular lattices is not only a promising route toward the fabrication of molecular lithography masks over macroscopic surface areas, but also represents an intriguing model system that enables the direct real-time observation of interface-related dynamic phenomena such as adsorption, desorption, and diffusion that are hardly accessible in other lattice-forming systems. In this work, we employ in situ high-speed atomic force microscopy to investigate the development of mixed DNA origami monolayers consisting of DNA origami triangles with threefold symmetry in the presence of rectangular DNA origami impurities with fourfold symmetry. The dynamic formation and annealing of the resulting defects is monitored in dependence of the triangle-to-rectangle ratio and correlated with the achieved lattice order. We find that the overall order of the formed DNA origami monolayer is rather resilient with regard to the presence of impurities. We even find indications that the deliberate addition of impurities at low concentrations may lead to slightly improved lattice order, presumable because they facilitate the dynamic rearrangement of neighboring lattice triangles and thus aid the annealing of non-impurity defects. Deliberate doping of DNA origami lattices with differently shaped impurities during assembly may thus provide a route toward further enhancing lattice quality via impurity-assisted annealing of lattice defects.

Abstract
Structural DNA nanotechnology has recently gained significant momentum, as diverse design tools for producing custom DNA shapes have become more and more accessible to numerous laboratories worldwide. Most commonly, researchers are employing a scaffolded DNA origami technique by "sculpting" a desired shape from a given lattice composed of packed adjacent DNA helices. Albeit relatively straightforward to implement, this approach contains its own apparent restrictions. First, the designs are limited to certain lattice types. Second, the long scaffold strand that runs through the entire structure has to be manually routed. Third, the technique does not support trouble-free fabrication of hollow single-layer structures that may have more favorable features and properties compared to objects with closely packed helices, especially in biological research such as drug delivery. In this focused review, we discuss the recent development of wireframe DNA nanostructures-methods relying on meshing and rendering DNA-that may overcome these obstacles. In addition, we describe each available technique and the possible shapes that can be generated. Overall, the remarkable evolution in wireframe DNA structure design methods has not only induced an increase in their complexity and thus expanded the prevalent shape space, but also already reached a state at which the whole design process of a chosen shape can be carried out automatically. We believe that by combining cost-effective biotechnological mass production of DNA strands with top-down processes that decrease human input in the design procedure to minimum, this progress will lead us to a new era of DNA nanotechnology with potential applications coming increasingly into view.

Abstract
Self-assembled DNA nanostructures have potential applications in therapeutics, diagnostics, and synthetic biology. A challenge in using DNA nanostructures in biological environments or cell culture, however, is that they may be degraded by enzymes found in these environments, such as nucleases. Such degradation can be slowed by introducing alternative substrates for nucleases, or by coating nanostructures with membranes or peptides. Here we demonstrate a means by which degradation can be reversed in situ through the repair of nanostructure defects. To demonstrate this effect, we show that degradation rates of DNA nanotubes, micron-scale self-assembled structures, are at least 4-fold lower in the presence of tiles that can repair nanotube defects during the degradation process. Micrographs of nanotubes show that tiles from solution incorporate into nanotubes and that this incorporation increases nanotube lifetime to several days in serum. We use experimental data to formulate a simple model of nanostructure self-healing. This model suggests how introducing even a relatively low rate of repair could allow a nanostructure to survive almost indefinitely because of a dynamic equilibrium between microscale repair and degradation processes. The ability to repair nanostructures could thus allow particular structures or devices to operate for long periods of time and might offer a single means to resist different types of chemical degradation.
