Abstract
![]()
DNA-based nanostructures have been
widely used in various applications
due to their structural diversity, programmability, and uniform structures.
Their intrinsic biocompatibility and biodegradability further motivates
the investigation of DNA-based nanostructures as delivery vehicles.
Incorporating AS1411 aptamers into DNA pyramids leads to enhanced
intracellular uptake and selectively inhibits the growth of cancer
cells, achieved without the use of transfection reagents. Furthermore,
aptamer-displaying pyramids are found to be substantially more resistant
to nuclease degradation than single-stranded aptamers. These findings,
along with their modularity, reinforce the potential of DNA-based
nanostructures for therapeutic applications.

Abstract
Peptide-functionalized DNA nano-objects selectively target mitochondria and the nucleus by means of nanoneedle-assisted delivery. This technology preserves the cell viability and structural integrity of nanostructures and assists the nano-objects in escaping degradation by endocytosis. This method opens up a new avenue for further in vitro studies of intracellular behaviors of DNA assemblies and their interactions in specific organelles.

Abstract
The unique programmability of nucleic acids offers versatility and flexibility in the creation of self-assembled DNA nanostructures. To date, many three-dimensional DNA architectures of varying sizes and shapes have been precisely formed. Their biocompatibility, biodegradability and high intrinsic stability in physiological environments emphasize their emerging use as carriers for drug and gene delivery. Furthermore, DNA nanocarriers have been shown to enter cells efficiently and without the aid of transfection reagents. A key strength of DNA nanocarriers over other delivery systems is their modularity and their ability to control the spatial distribution of cargoes and ligands. Optimizing DNA nanocarrier properties to dictate their localization, uptake and intracellular trafficking is also possible. This review presents design considerations for DNA nanocarriers and examples of their use in the context of therapeutic delivery applications. The assembly of DNA nanocarriers and approaches for loading and releasing cargo are described. The stability and safety of DNA nanocarriers are also discussed, with particular attention to the in vivo physiological environment. Mechanisms of cellular uptake and intracellular trafficking are examined, and the paper concludes with strategies to enhance the delivery efficiency of DNA nanocarriers.

Abstract
DNA origami structures can be programmed into arbitrary shapes with nanometer scale precision, which opens up numerous attractive opportunities to engineer novel functional materials. One intriguing possibility is to use DNA origamis for fully tunable, targeted, and triggered drug delivery. In this work, we demonstrate the coating of DNA origami nanostructures with virus capsid proteins for enhancing cellular delivery. Our approach utilizes purified cowpea chlorotic mottle virus capsid proteins that can bind and self-assemble on the origami surface through electrostatic interactions and further pack the origami nanostructures inside the viral capsid. Confocal microscopy imaging and transfection studies with a human HEK293 cell line indicate that protein coating improves cellular attachment and delivery of origamis into the cells by 13-fold compared to bare DNA origamis. The presented method could readily find applications not only in sophisticated drug delivery applications but also in organizing intracellular reactions by origami-based templates.

Abstract
Oligodeoxynucleotides (ODNs) containing unmethylated CpG dinucleotide motifs are agonists of Toll-like receptor 9 and are currently being investigated for use as vaccine adjuvants through the promotion of type I immunity. Several classes of ODN have been developed which differ in their propensity to aggregate, which in turn alters cytokine profiles and cellular subsets activated. Although aggregation state is correlated with the change in cytokine response, it is unknown if this results from a change in the number of ODNs available for binding and/or the possible engagement of multiple TLR9 molecules. Here, we examined the role of ligand valency on the activation of TLR9 through the synthesis of ODN-poly(acrylic acid) (PAA) conjugates. The compositions and size of the conjugates were characterized by UV-vis spectroscopy, proton nuclear magnetic resonance, gel permeation chromatography and dynamic light scattering. Enzyme-linked immunosorbent assays of cytokine secretion by murine-like macrophages indicate that these ODN-PAA polymer conjugates show enhanced immunostimulation at 100-fold lower concentrations than those required for ODN alone, for both TNF-α and IL-6 release, and are more potent than any other previously reported multivalent ODN constructs. Increasing valency was shown to significantly enhance cytokine expression, particularly for IL-6. Knockdown by siRNA demonstrates that these polymer conjugates are specific to TLR9. Our results define valency as a critical design parameter and polymer conjugation as an advantageous strategy for producing ODN immunomodulatory agents.

Abstract
There has been tremendous interest in constructing nanostructures by exploiting the unparalleled ability of DNA molecules in self-assembly. We have seen the appearance of many fantastic, "art-like" DNA nanostructures in one, two, or three dimensions during the last two decades. More recently, much attention has been directed to the use of these elegant nanoobjects for applications in a wide range of areas. Among them, diagnosis and therapy (i.e., theranostics) are of particular interest given the biological nature of DNA. One of the major barricades for the biosensor design lies in the restricted target accessibility at the solid-water interface. DNA nanotechnology provides a convenient approach to well control the biomolecule-confined surface to increase the ability of molecular recognition at the biosensing interface. For example, tetrahedral DNA nanostructures with thiol modifications can be self-assembled at the gold surface with high reproducibility. Since DNA tetrahedra are highly rigid and well-defined structures with atomic precision and versatile functionality, they provide scaffolds for anchoring of a variety of biomolecular probes (DNA, aptamers, peptides, and proteins) for biosensing. Significantly, this DNA nanostructure-based biosensing platform greatly increases target accessibility and improves the sensitivity for various types of molecular targets (DNA, RNA, proteins, and small molecules) by several orders of magnitude. In an alternative approach, DNA nanostructures provide a framework for the development of dynamic nanosensors that can function inside the cell. DNA tetrahedra are found to be facilely cell permeable and can sense and image specific molecules in cells. More importantly, these DNA nanostructures can be efficient drug delivery nanocarriers. Since they are DNA molecules by themselves, they have shown excellent cellular biocompatibility with minimal cytotoxicity. As an example, DNA tetrahedra tailored with CpG oligonucleotide drugs have shown greatly improved immunostimulatory effects that makes them a highly promising nanomedicine. By taking them together, we believe these functionalized DNA nanostructures can be a type of intelligent theranostic nanodevice for simultaneous sensing, diagnosis, and therapy inside the cell.

Abstract
Natural polymers are able to self-assemble into versatile nanostructures based on the information encoded into their primary structure. The structural richness of biopolymer-based nanostructures depends on the information content of building blocks and the available biological machinery to assemble and decode polymers with a defined sequence. Natural polypeptides comprise 20 amino acids with very different properties in comparison to only 4 structurally similar nucleotides, building elements of nucleic acids. Nevertheless the ease of synthesizing polynucleotides with selected sequence and the ability to encode the nanostructural assembly based on the two specific nucleotide pairs underlay the development of techniques to self-assemble almost any selected three-dimensional nanostructure from polynucleotides. Despite more complex design rules, peptides were successfully used to assemble symmetric nanostructures, such as fibrils and spheres. While earlier designed protein-based nanostructures used linked natural oligomerizing domains, recent design of new oligomerizing interaction surfaces and introduction of the platform for topologically designed protein fold may enable polypeptide-based design to follow the track of DNA nanostructures. The advantages of protein-based nanostructures, such as the functional versatility and cost effective and sustainable production methods provide strong incentive for further development in this direction.

Abstract
Synthetic unmethylated cytosine-guanine (CpG) oligodeoxynucleotides (CpG ODNs) possess high immunostimulatory activity and have been widely used as a therapeutic tool for various diseases including infection, allergies, and cancer. A variety of nanocarriers have been developed for intracellular delivery of CpG ODNs that are otherwise nonpermeable through the cellular membrane. For example, previous studies showed that gold nanoparticles (AuNPs) could efficiently deliver synthetic thiolated CpG ODNs into cultured cells and induce expression of proinflammatory cytokines. Nevertheless, the necessity of using thiolated CpG ODNs for the modification of AuNPs inevitably complicates the synthesis of the nanoconjugates and increases the cost. A new approach is demonstrated for facile assembly of AuNP-CpG nanoconjugates for cost-effective drug delivery. It is found that non-thiolated, diblock ODNs containing a CpG motif and a poly-adenine (polyA) tail can readily self-assemble on the surface of AuNPs with controllable and tunable density. Such nanoconjugates are efficiently delivered into RAW264.7 cells and induce immune response in a Toll-like receptor 9 (TLR9)-dependent manner. Under optimal conditions, polyA-CpG-AuNPs show significantly higher immunostimulatory activity than their thiolated counterpart. In addition, the immunostimulatory activity of CpG-AuNPs can be modulated by varying the length of the polyA tail. In vivo induction of immune responses in mice is demonstrated by using polyA-tailed CpG-AuNP nanoconjugates.

The ability to self-assemble one-dimensional DNA building blocks into two- and three-dimensional nanostructures via DNA/RNA nanotechnology has led to broad applications in bioimaging, basic biological mechanism studies, disease diagnosis, and drug delivery. However, the cellular uptake of most nucleic acid nanostructures is dependent on passive delivery or the enhanced permeability and retention effect, which may not be suitable for certain types of cancers, especially for treatment in vivo. To meet this need, we have constructed a multifunctional aptamer-based DNA nanoassembly (AptNA) for targeted cancer therapy. In particular, we first designed various Y-shaped functional DNA domains through predesigned base pair hybridization, including targeting aptamers, intercalated anticancer drugs, and therapeutic antisense oligonucleotides. Then these functional DNA domains were linked to an X-shaped DNA core connector, termed a building unit, through the complementary sequences in the arms of functional domains and connector. Finally, hundreds (~100-200) of these basic building units with 5'-modification of acrydite groups were further photo-cross-linked into a multifunctional and programmable aptamer-based nanoassembly structure able to take advantage of facile modular design and assembly, high programmability, excellent biostability and biocompatibility, as well as selective recognition and transportation. With these properties, AptNAs were demonstrated to have specific cytotoxic effect against leukemia cells. Moreover, the incorporation of therapeutic antisense oligonucleotides resulted in the inhibition of P-gp expression (a drug efflux pump to increase excretion of anticancer drugs) as well as a decrease in drug resistance. Therefore, these multifunctional and programmable aptamer-based DNA nanoassemblies show promise as candidates for targeted drug delivery and cancer therapy.

Abstract
We report sensitization of a cellular signaling pathway by addition of functionalized DNA nanostructures. Signaling by transforming growth factor β (TGFβ) has been shown to be dependent on receptor clustering. By patterning a DNA nanostructure with closely spaced peptides that bind to TGFβ receptor, we observe increased sensitivity of NMuMG cells to TGFβ ligand. This is evidenced by translocation of secondary messenger proteins to the nucleus and stimulation of an inducible luciferase reporter at lower concentrations of TGFβ ligand. We believe this represents an important initial step toward realization of DNA as a self-assembling and biologically compatible material for use in tissue engineering and drug delivery.

Abstract
We have applied self-assembled DNA tetrahedral nanostructures for the precise and tunable control of the gain in an optofluidic fluorescence resonance energy transfer (FRET) laser. By adjusting the ratio of the donor and the acceptor attached to the tetrahedral vertices, 3.8 times reduction in the lasing threshold and 28-fold enhancement in the lasing efficiency were demonstrated. This work takes advantage of the self-recognition and self-assembly capabilities of biomolecules with well-defined structures and addressability, enabling nano-engineering of the laser down to the molecular level.

Abstract
Self-assembled DNA nanostructures have emerged as a type of nano-biomaterials with precise structures, versatile functions and numerous applications. One particularly promising application of these DNA nanostructures is to develop universal nanocarriers for smart and targeted drug delivery. DNA is the genetic material in nature, and inherently biocompatible. Nevertheless, cell membranes are barely permeable to naked DNA molecules, either single- or double- stranded; transport across the cell membrane is only possible with the assistance of transfection agents. Interestingly, recent studies revealed that many DNA nanostructures could readily go into cells with high cell uptake efficiency. In this Progress Report, we will review recent advances on using various DNA nanostructures, e.g., DNA nanotubes, DNA tetrahedra, and DNA origami nanorobot, as drug delivery nanocarriers, and demonstrate several examples aiming at therapeutic applications with CpG-based immunostimulatory and siRNA-based gene silencing oligonucleotides.

Abstract
The unprecedented development of DNA nanotechnology has caused DNA self-assembly to attract close attention in many disciplines. In this research news article, the employment of DNA self-assembly in the fields of materials science and nanotechnology is described. DNA self-assembly can be used to prepare bulk-scale hydrogels and 3D macroscopic crystals with nanoscale internal structures, to induce the crystallization of nanoparticles, to template the fabrication of organic conductive nanomaterials, and to act as drug delivery vehicles for therapeutic agents. The properties and functions are fully tunable because of the designability and specificity of DNA assembly. Moreover, because of the intrinsic dynamics, DNA self-assembly can act as a program switch and can efficiently control stimuli responsiveness. We highlight the power of DNA self-assembly in the preparation and function regulation of materials, aiming to motivate future multidisciplinary and interdisciplinary research. Finally, we describe some of the challenges currently faced by DNA assembly that may affect the functional evolution of such materials, and we provide our insights into the future directions of several DNA self-assembly-based nanomaterials.

Abstract
While the remarkable chemical and biological properties of DNA have been known for decades, these properties have only been imparted into materials with unprecedented function much more recently. The inimitable ability of DNA to form programmable, complex assemblies through stable, specific, and reversible molecular recognition has allowed the creation of new materials through DNA's ability to control a material's architecture and properties. In this review we discuss recent progress in how DNA has brought unmatched function to materials, focusing specifically on new advances in delivery agents, devices, and sensors.

Abstract
Simple chemical modifications to oligonucleotide ends with hexaethylene glycol and hexanediol are shown to significantly increase nuclease resistance under serum conditions. The modified oligonucleotides were used to construct DNA prismatic cages in a single step and in quantitative yield. These cages further stabilize their strands towards nucleases, with lifetimes of 62 hours in serum. The cages contain a large number of single-stranded regions for functionalization, illustrating their versatility for biological applications.

Abstract
We review the current developments of DNA-based nanostructures for drug delivery, immunotherapy, diagnostics and molecular biology. DNA is a powerful building block, which by the nature of predictable base pairing, allows the creation of molecular scaffolds, cages and multifunctional carriers with nanoscale dimensions. These engineered constructs have unsurpassed structural qualities such as full control over size, shape and dispersity. Site-specific surface modification enables the presentation of biomolecules at defined distances and stochiometries, which allows tailored cell targeting and substance delivery on demand. As the first successful in vivo applications of DNA nanostructures have recently been demonstrated, we now expect a burst of biomedical studies involving this rapidly progressing technology.

Abstract
Nanotechnology has allowed the construction of various nanostructures for applications, including biomedicine. However, a simple target-specific, economical, and biocompatible drug delivery platform with high maximum tolerated doses is still in demand. Here, we report aptamer-tethered DNA nanotrains (aptNTrs) as carriers for targeted drug transport in cancer therapy. Long aptNTrs were self-assembled from only two short DNA upon initiation by modified aptamers, which worked like locomotives guiding nanotrains toward target cancer cells. Meanwhile, tandem "boxcars" served as carriers with high payload capacity of drugs that were transported to target cells and induced selective cytotoxicity. aptNTrs enhanced maximum tolerated dose in nontarget cells. Potent antitumor efficacy and reduced side effects of drugs delivered by biocompatible aptNTrs were demonstrated in a mouse xenograft tumor model. Moreover, fluorophores on nanotrains and drug fluorescence dequenching upon release allowed intracellular signaling of nanotrains and drugs. These results make aptNTrs a promising targeted drug transport platform for cancer theranostics.

Abstract
DNA methylation, catalyzed by methylases, plays a critical role in many biological processes, and many methylases have been regarded as promising targets for antimicrobial drugs. In this work, we report a stimulus responsive, self-regulating anticancer drug release platform, comprising a multifunctional DNA that upon methylation by methyltransferase (MTase) releases 5-fluorouracil (5-Fu) and in turn inhibits subsequent expression of MTase. The multifunctional DNA with anticancer drug are first methylated by DNA adenine methylation (DAM) methyltransferase (MTase) and then cut by the methylation-sensitive restriction endonuclease Dpn I. Removal of duplex from the functional DNA by the methylation/cleavage process will release the anticancer drug, resulting in inhibition of the activity of DAM in turn. Consequently, the enzyme activity of DAM MTase can be self-regulated. Furthermore, we found that the inhibition efficiency of 5-Fu significantly increase as it is functionalized with DNA.

Abstract
Background Reversible assembly and disassembly of nanostructures has important function in controllable construction of nanodevices. There are several methods to achieve reversible assembly/disassembly, such as pH, temperature, DNA hybridization and so on. Among these methods, pH driven reversible assembly presents superiority due to its ease-of-use and no waste produced. Herein we report a novel design that use two single-stranded (ss) DNAs wrapped single walled carbon nanotubes (SWCNTs) for the pH controlled assembly of SWCNTs without generation of waste. Results Both of the two DNAs with a same wrapping sequence of d(GT)20 and different free terminals showed a very high tendency to wrap around carbon nanotubes. The assembly was driven by the hybridization between the two free terminals of wrapped DNAs on the neighboring SWCNTs: i-motif (four-stranded C-quadruplex) and its complemental stranded G-quadruplex which would form tight tetraplexes and break the hybridization under slightly acidic conditions. Thus the assembly and disassembly are reversibly controlled by pH. And this assembly/disassembly process can be easily distinguished by naked eyes. Gel electrophoresis and Atomic Force Microscope are used to demonstrate the assembly and disassembly of SWCNTs at different pH. Conclusions A novel pH induced reversible assembly and disassembly of SWCNTs was realized which may have potential applications in the area of controlled assembly of nanostructures.

Abstract
Non-Watson-Crick base pairing provides an in situ approach for actuation of DNA nanostructures through responses to solution conditions. Here we demonstrate this concept by using physiologically-relevant changes in pH to regulate DNA pyramid assembly/disassembly and to control the release of protein cargo.

Abstract
Living systems have evolved a variety of nanostructures to control the molecular interactions that mediate many functions including the recognition of targets by receptors, the binding of enzymes to substrates, and the regulation of enzymatic activity. Mimicking these structures outside of the cell requires methods that offer nanoscale control over the organization of individual network components. Advances in DNA nanotechnology have enabled the design and fabrication of sophisticated one-, two- and three-dimensional (1D, 2D, and 3D) nanostructures that utilize spontaneous and sequence-specific DNA hybridization. Compared with other self-assembling biopolymers, DNA nanostructures offer predictable and programmable interactions and surface features to which other nanoparticles and biomolecules can be precisely positioned. The ability to control the spatial arrangement of the components while constructing highly organized networks will lead to various applications of these systems. For example, DNA nanoarrays with surface displays of molecular probes can sense noncovalent hybridization interactions with DNA, RNA, and proteins and covalent chemical reactions. DNA nanostructures can also align external molecules into well-defined arrays, which may improve the resolution of many structural determination methods, such as X-ray diffraction, cryo-EM, NMR, and super-resolution fluorescence. Moreover, by constraint of target entities to specific conformations, self-assembled DNA nanostructures can serve as molecular rulers to evaluate conformation-dependent activities. This Account describes the most recent advances in the DNA nanostructure directed assembly of biomolecular networks and explores the possibility of applying this technology to other fields of study. Recently, several reports have demonstrated the DNA nanostructure directed assembly of spatially interactive biomolecular networks. For example, researchers have constructed synthetic multienzyme cascades by organizing the position of the components using DNA nanoscaffolds in vitro or by utilizing RNA matrices in vivo. These structures display enhanced efficiency compared with the corresponding unstructured enzyme mixtures. Such systems are designed to mimic cellular function, where substrate diffusion between enzymes is facilitated and reactions are catalyzed with high efficiency and specificity. In addition, researchers have assembled multiple choromophores into arrays using a DNA nanoscaffold that optimizes the relative distance between the dyes and their spatial organization. The resulting artificial light-harvesting system exhibits efficient cascading energy transfers. Finally, DNA nanostructures have been used as assembly templates to construct nanodevices that execute rationally designed behaviors, including cargo loading, transportation, and route control.

Abstract
Right out of the (logic) gate: Logic gates made from 3D DNA nanotetrahedra were constructed that are responsive to various ions, small molecules, and short strands of DNA. By including dynamic sequences in one or more edges of the tetrahedra, a FRET signal can be generated in the manner of AND, OR, XOR, and INH logic gates, as well as a half-adder circuit. These DNA logic gates were also applied to intracellular detection of ATP.

Abstract
Safe and effective vaccines offer the best intervention for disease control. One strategy to maximize vaccine immunogenicity without compromising safety is to rationally design molecular complexes that mimic the natural structure of immunogenic microbes but without the disease-causing components. Here we use highly programmable DNA nanostructures as platforms to assemble a model antigen and CpG adjuvants together into nanoscale complexes with precise control of the valency and spatial arrangement of each element. Our results from immunized mice show that compared to a mixture of antigen and CpG molecules, the assembled antigen-adjuvant-DNA complexes induce strong and long-lasting antibody responses against the antigen without stimulating a reaction to the DNA nanostructure itself. This result demonstrates the potential of DNA nanostructures to serve as general platforms for the rational design and construction of a variety of vaccines.

Abstract
Although a multitude of promising anti-cancer drugs have been developed over the past 50 years, effective delivery of the drugs to diseased cells remains a challenge. Recently, nanoparticles have been used as drug delivery vehicles due to their high delivery efficiencies and the possibility to circumvent cellular drug resistance. However, the lack of biocompatibility and inability to engineer spatially addressable surfaces for multi-functional activity remains an obstacle to their widespread use. Here we present a novel drug carrier system based on self-assembled, spatially addressable DNA origami nanostructures that confronts these limitations. Doxorubicin, a well-known anti-cancer drug, was non-covalently attached to DNA origami nanostructures through intercalation. A high level of drug loading efficiency was achieved, and the complex exhibited prominent cytotoxicity not only to regular human breast adenocarcinoma cancer cells (MCF 7), but more importantly to doxorubicin-resistant cancer cells, inducing a remarkable reversal of phenotype resistance. With the DNA origami drug delivery vehicles, the cellular internalization of doxorubicin was increased, which contributed to the significant enhancement of cell-killing activity to doxorubicin-resistant MCF 7 cells. Presumably, the activity of doxorubicin-loaded DNA origami inhibits lysosomal acidification, resulting in cellular redistribution of the drug to action sites. Our results suggest that DNA origami has immense potential as an efficient, biocompatible drug carrier and delivery vehicle in the treatment of cancer.

Abstract
The immunostimulatory activity of phosphodiester DNA containing unmethylated cytosine-phosphate-guanine (CpG) dinucleotides, or CpG motifs, was significantly increased by the formation of Y-, X-, or dendrimer-like multibranched shape. These results suggest the possibility that the activity of CpG DNA is a function of the structural properties of branched DNA assemblies. To elucidate the relationship between them, we have designed and developed nanosized DNA assemblies in polypod-like structures (polypod-like structured DNA, or polypodna for short) using oligodeoxynucleotides (ODNs) containing CpG motifs and investigated their structural and immunological properties. Those assemblies consisting of three (tripodna) to eight (octapodna) ODNs were successfully obtained, but one consisting of 12 ODNs was not when 36-mer ODNs were annealed under physiological sodium chloride concentration. High-speed atomic force microscopy revealed that these assemblies were in polypod-like structures. The apparent size of the products was about 10 nm in diameter, and there was an increasing trend with an increase in ODN length or with the pod number. Circular dichroism spectral data showed that DNA in polypodna preparations were in the B-form. The melting temperature of polypodna decreased with increasing pod number. Each polypodna induced the secretion of tumor necrosis factor-α and interleukin-6 from macrophage-like RAW264.7 cells, with the greatest induction by those with hexa- and octapodna. Increasing the pod number increased the uptake by RAW264.7 cells but reduced the stability in serum. These results indicate that CpG DNA-containing polypodna preparations with six or more pods are a promising nanosized device with biodegradability and high immunostimulatory activity.
