Bio-inspired functional microcapsules stabilised with surfactants, copolymers, and nano/microparticles have attracted much attention in many fields from physical/chemical science to artificial cell engineering. Although the particle-stabilized microcapsules have advantages for their stability and rich ways for functionalisation such as surface chemical modifications and shape control of particles, versatile methods for their designable functionalisation are desired to expand their possibilities. Here, we report a DNA-based microcapsule composed of a water-in-oil microdroplet stabilised with amphiphilised DNA origami nanoplates. By utilising function programmability achieved by DNA nanotechnology, the DNA nanoplates were designed as a nanopore device for ion transportation as well as the interface stabiliser. Microscopic observations showed that the microcapsule formed by amphiphilic DNA nanoplates accumulated at the oil-water interface. Ion current measurements demonstrated that pores in the nanoplates functioned as ion channels. These findings provide a general strategy for programmable designing of microcapsules for engineering artificial cells and molecular robots.<br>

DNA nanotechnology provides an excellent foundation for diverse nanoscale structures that can be used in various bioapplications and materials research. Among all existing DNA assembly techniques, DNA origami proves to be the most robust one for creating custom nanoshapes. Since its invention in 2006, building from the bottom up using DNA advanced drastically, and therefore, more and more complex DNA-based systems became accessible. So far, the vast majority of the demonstrated DNA origami frameworks are static by nature; however, there also exist dynamic DNA origami devices that are increasingly coming into view. In this review, we discuss DNA origami nanostructures that exhibit controlled translational or rotational movement when triggered by predefined DNA sequences, various molecular interactions, and/or external stimuli such as light, pH, temperature, and electromagnetic fields. The rapid evolution of such dynamic DNA origami tools will undoubtedly have a significant impact on molecular-scale precision measurements, targeted drug delivery and diagnostics; however, they can also play a role in the development of optical/plasmonic sensors, nanophotonic devices, and nanorobotics for numerous different tasks.

Abstract MicroRNAs are involved in the crucial processes of development and diseases and have emerged as a new class of biomarkers. The field of DNA nanotechnology has shown great promise in the creation of novel microRNA biosensors that have utility in lab-based biosensing and potential for disease diagnostics. In this Survey and Summary, we explore and review DNA nanotechnology approaches for microRNA detection, surveying the literature for microRNA detection in three main areas of DNA nanostructures: DNA tetrahedra, DNA origami, and DNA devices and motifs. We take a critical look at the reviewed approaches, advantages and disadvantages of these methods in general, and a critical comparison of specific approaches. We conclude with a brief outlook on the future of DNA nanotechnology in biosensing for microRNA and beyond.

Structural Dna Nanotechnology

Structural DNA nanotechnology is beginning to emerge as a widely accessible research tool to mechanistically study diverse biophysical processes. Enabled by scaffolded DNA origami in which a long single strand of DNA is weaved throughout an entire target nucleic acid assembly to ensure its proper folding, assemblies of nearly any geometric shape can now be programmed in a fully automatic manner to interface with biology on the 1–100-nm scale. Here, we review the major design and synthesis principles that have enabled the fabrication of a specific subclass of scaffolded DNA origami objects called wireframe assemblies. These objects offer unprecedented control over the nanoscale organization of biomolecules, including biomolecular copy numbers, presentation on convex or concave geometries, and internal versus external functionalization, in addition to stability in physiological buffer. To highlight the power and versatility of this synthetic structural biology approach to probing molecular and cellular biophysics, we feature its application to three leading areas of investigation: light harvesting and nanoscale energy transport, RNA structural biology, and immune receptor signaling, with an outlook toward unique mechanistic insight that may be gained in these areas in the coming decade.

Nanofiltration membranes act an important role in the advanced water treatment as well as waste water reclamation and other industrial separations. Therefore, an understanding of the factors affecting NF separation and membrane fouling in high-pressure membrane systems is needed. Recent studies have shown that membrane surface morphology and structure as well as surface chemical characteristics influence permeability, rejection, and fouling behavior of nanofiltration (NF) membranes. A comprehensive literature review is reported, targeting the physical-chemical characteristics of NF membrane affecting separation and fouling, including pore size, porosity, surface morphology (measured as roughness), surface charge, and hydrophobicity/ hydrophilicity.

AbstractDNA origami, in which a long scaffold strand is assembled with a many short staple strands into parallel arrays of double helices, has proven a powerful method for custom nanofabrication. However, currently the design and optimization of custom 3D DNA-origami shapes is a barrier to rapid application to new areas. Here we introduce a modular barrel architecture, and demonstrate hierarchical assembly of a 100 megadalton DNA-origami barrel of ~90 nm diameter and ~250 nm height, that provides a rhombic-lattice canvas of a thousand pixels each, with pitch of ~8 nm, on its inner and outer surfaces. Complex patterns rendered on these surfaces were resolved using up to twelve rounds of Exchange-PAINT super-resolution microscopy. We envision these structures as versatile nanoscale pegboards for applications requiring complex 3D arrangements of matter, which will serve to promote rapid uptake of this technology in diverse fields beyond specialist groups working in DNA nanotechnology.

Abstract DNA as life’s genetic material has been widely investigated around the world. In recent years, with the fiery researches on nanomaterials, it also plays an important role in the development of material science due to its extraordinary molecular recognition capability and prominent structural features. In this mini review, we mainly overview the recent progresses of DNA guiding self-assembled nanostructures and nanofabrication. Typical DNA tile-based assembly and DNA origami nanotechnologies are presented, utilizing the recent 3D topology methods to fabricate multidimensional structures with unique properties. Then the site-specific nanomaterials synthesis and nano-DNA recognition on different DNA scaffolds/templates are demonstrated with excellent addressability, biocompatibility and structural programmability. Various nanomaterials, such as metals, carbon family materials, quantum dots, metal-organic frameworks, and DNA-based liquid crystals are briefly summarized. Finally, the present limitation and future promising development directions are discussed in conclusion and perspective. We wish this review would provide useful information toward the broader scientific interests in DNA nanotechnology.

Since the arrival of DNA nanotechnology nearly 40 years ago, the field has progressed from its beginnings of envisioning rather simple DNA structures having a branched, multi-strand architecture into creating beautifully complex structures comprising hundreds or even thousands of unique strands, with the possibility to exactly control the positions down to the molecular level. While the earliest construction methodologies, such as simple Holliday junctions or tiles, could reasonably be designed on pen and paper in a short amount of time, the advent of complex techniques, such as DNA origami or DNA bricks, require software to reduce the time required and propensity for human error within the design process. Where available, readily accessible design software catalyzes our ability to bring techniques to researchers in diverse fields and it has helped to speed the penetration of methods, such as DNA origami, into a wide range of applications from biomedicine to photonics. Here, we review the historical and current state of CAD software to enable a variety of methods that are fundamental to using structural DNA technology. Beginning with the first tools for predicting sequence-based secondary structure of nucleotides, we trace the development and significance of different software packages to the current state-of-the-art, with a particular focus on programs that are open source.
