Available in PDF, EPUB and Kindle. Book excerpt: "Block copolymers have widespread use in areas such as luminescence, photovoltaics, electronics, optics, shape memory, self healing, stimuli-responsiveness, photonics, and drug delivery due to their predictable, ordered nanostructures. However, block copolymer materials are usually restricted to highly symmetric spherical, cylindrical, lamellar, and vesicular morphologies, resulting from the non-covalent interactions that direct their assembly. Recent interest, inspired by natural systems, has emerged to break the symmetry in polymer self-assembly to achieve materials with new and unusual functional properties. To break the symmetry of polymer assembly, patchy particles, Janus particles, multicompartment particles, and lithography have been employed. Although these methods of polymer assembly have improved the range of polymer architectures, they have limited control of the compartmentalization and orientation of the binding sites on the particle surface. In contrast, DNA nanotechnology harnesses Watson-Crick-Franklin base pairing to create highly specific and programmable assemblies at the nanoscale. Therefore, transferring a pattern of DNA strands from a DNA nanostructure onto polymer particles ("printing") combines the materials properties of polymers with the high structural control of DNA nanotechnology. In this thesis, advances to make new DNA polymer hybrid materials are employed-with an emphasis of printing DNA patterns on polymer particle surfaces. First, the use of DNA cubes as a 2D printing press, placing DNA strands with controlled sequence, valency, and patterns on the surface of block copolymer micelles and spherical nucleic acids will be investigated. Second, using sequence-defined polymers, a polymer particle that can be assembled inside a DNA cube with a 3D DNA pattern attached will be examined. Again, these printed strands have controlled DNA sequence, valency, and pattern on the surface. Furthermore, these 3D cube printed particles can have polymers attached, with click chemistry, to the surface to change particle properties. All these cube printing methods are modular; changing the polymer composition of the DNA printed particles can further give assemblies with given polymer types at a given position, further tuning the material properties. Lastly, spherical nucleic acids will be used as a nanoreactor to incorporate hydrophobic drug-polymer conjugates for controlled drug release. These materials will be useful for drug delivery and building blocks for asymmetric polymer patterning. Overall, these DNA-polymer materials can be used to make new hierarchical and functional materials through their programmable assembly"--

Available in PDF, EPUB and Kindle. Book excerpt: "DNA is an exceptional material for bottom-up assembly of nanostructures with arbitrary shapes and high level of complexity due to its programmability, predictability and biocompatibility. Variety of well-defined DNA nanostructures ranging from a few nanometers to microns can be constructed with unparalleled precision and control. Beyond the self-assembly perspective, chemists have discovered that DNA can provide an excellent template for chemical reactions with high selectivity because it can significantly increase the local concentration of appended reactants. This thesis aims to explore the possibility of using minimalist DNA nanostructures as templates for chemical transformations to generate unique DNA-hybrid materials. First, the use of DNA micelle as a new reaction platform to enable DNA functionalization with highly hydrophobic molecules in aqueous media is investigated. The hydrophobic core of the DNA micelle can act as a reaction auxiliary that facilitates the conjugation of complementary DNA strands to hydrophobic units. Due to the sequence-controlled properties of each component used for DNA micelles assembly, reactivity can be easily tuned and studied. Second, the use of DNA nanostructures for templating reactions is expanded further to two-dimensional (2D) chemical transfer of DNA strand patterns, from a multi-arm DNA junction to a small molecule. This “printing” approach is highly modular, and it allows the resulting branched DNA-small molecule can be controlled precisely in terms of DNA sequences, valency and directionalities (5’-3’). Finally, a three-dimensional (3D) DNA “printing” method using minimal DNA cages to well-defined polymeric materials is presented. The organization of DNA strands on these scaffolds creates DNA strand patterns that can be efficiently transferred to a crosslinked polymer core inside the cage with precise control over the number, directionality, geometry and sequence anisotropy of DNA strands. The resulting DNA-imprinted polymer nanoparticles can be programmed to assemble into asymmetric higher order structures using DNA hybridization. These unique DNA-hybrid molecules can find numerous potential applications. The work presented in chapter 2 opens an opportunity to synthesize a variety of DNA hybrid materials with hydrophobic molecules, which are useful in DNA and small molecule therapeutic delivery, diagnostics, nanopore formation and self-assembly. Branched DNA-imprinted small molecules demonstrated in chapter 3 can be useful in the field of DNA nanotechnology as building blocks for wireframe DNA nanostructures, branching staple strands in DNA origami and tunable templates for material organization. The DNA-imprinted polymeric particles in chapter 4 can serve as precisely-defined “multi-arm junctions” to create highly complex structures in a predictable manner. They can also be useful in applications such as drug delivery, barcoded diagnostic or building blocks for non-centrosymmetric polymer patterning. Overall, the approaches introduced in this thesis can be used to make functional DNA-hybrid structures, with an emphasis on simplifying synthetic efforts while retaining structural complexity"--

Available in PDF, EPUB and Kindle. Book excerpt: "DNA is used for the storage and propagation of genetic information in all living organisms. It is the programmability and molecular recognition properties of DNA which make this possible. Taking advantage of these properties, researchers have developed DNA self-assembly as a highly predictable method of bottom-up nanofabrication. The resulting nanostructures have the potential to solve important problems in diverse fields, from nanophotonics to gene therapy. To date most DNA nanostructures have been made purely from unmodified, natural DNA. To achieve structural complexity needed for functional devices, researchers have created intricate designs which often require a large number of DNA strands of different sequence,with increased cost and assembly error rates. This thesis examines the chemical modification of nucleic acids and their integration into DNA nanostructures. This approach is expected to simplify design and significantly reduce the number of DNA components, while adding functional complexity. Specifically, the introduction of orthogonal supramolecular interactions to DNA nanostructures and the resultant properties of these hybrid systems is investigated. Firstly, the synthesis of novel dendritic DNA amphiphiles and their self-assembly properties are investigated. The site-specific positioning of the amphiphiles on a cubic DNA scaffold allows the anisotropic organization of hydrophobic 'residues', in a manner similar to the side-chains on a protein backbone. A new set of self-assembly rules is discovered, in which these nanostructures show a geometry-dependent inter- or intra-molecular association. This is used to create the first example of a DNA nanostructure which can encapsulate and release small molecule drugs, an important challenge in nanomedicine. Secondly, this synthetic methodology is developed to produce a family of DNA-polymer conjugates, with sequence-defined polymers appended to DNA. These conjugates exhibit tunable self-assembly properties, dependent on the sequence of monomers in the polymer portion. Finally, the modular synthetic approaches developed are used to produce novel gold-binding DNA conjugates. The organization of these on prismatic DNA scaffolds creates patterns of DNA strands which can be efficiently transferred to gold nanoparticles. This template-guided 'printing' approach provides control over the number, directionality, geometry and sequence asymmetry of DNA strands bound to gold nanoparticle. Overall, the development of new synthetically modified oligonucleotides and their incorporation into nanostructures is shown to augment the field of DNA nanotechnology, introducing protein-inspired interactions and providing new tools for the creation of functional nanodevices for applications in the fields of nanophotonics, nanoelectronics and biological sensing, as well as drug and oligonucleotide delivery." --

Download or read book Development and Evaluation of DNA Nanostructures for Cell Surface Engineering written by Brandon Davis and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cell membrane is a selectively permeable barrier that functions as the interface between the cytosol and extracellular space. It regulates cell behaviors by monitoring the extracellular space for soluble signaling molecules and biophysical cues. These cues trigger signaling pathways that are responsible for critical cell functions such as differentiation, proliferation, gene and protein expression, and even apoptosis. Thus, the ability to engineer the cell membrane holds great potential for various biomedical applications including cell therapy and regenerative medicine. Significant clinical advances illustrate the power of cell engineering to restore, enhance or impart cell functionality. Cells have been genetically altered to address genetic disorders and target highly evasive cancers by exploiting existing cell machinery. However, genetic engineering faces many technical challenges such as delivery efficiency as well as long-term safety and ethical concerns. Nongenetic engineering of the cell surface with prefabricated or in situ nanomaterials is an emerging field that seeks to provide an alternative to genetic engineering. One promising strategy to generate these nanomaterials is DNA nanotechnology. The objective of this dissertation is to explore a novel DNA-based nanomaterial approach for cell surface engineering and develop methods for nanostructure presentation on the surface of living cells. Nanoparticles were functionalized with polyvalent DNA ligands and evaluated for their ability to bind cells displaying complementary DNA receptors. A supramolecular nanostructure was designed and synthesized using DNA hybridization of DNA-polymer conjugates. The nanostructure was examined for its ability to present exogenous molecules on the cell surface for bidirectional signal amplification. Further, the formation of a polymeric nanocoating using the DNA-polymer nanostructure as a framing template was evaluated. The biocompatibility and stability of the nanocoating in physiological environments was assessed.

Book excerpt: As the genetic information storage vehicle, deoxyribonucleic acid (DNA) molecules are essential to all known living organisms and many viruses. It is amazing that such a large amount of information about how life develops can be stored in these tiny molecules. Countless scientists, especially some biologists, are trying to decipher the genetic information stored in these captivating molecules. Meanwhile, another group of researchers, nanotechnologists in particular, have discovered that the unique and concise structural features of DNA together with its information coding ability can be utilized for nano-construction efforts. This idea culminated in the birth of the field of DNA nanotechnology which is the main topic of this dissertation. The ability of rationally designed DNA strands to self-assemble into arbitrary nanostructures without external direction is the basis of this field. A series of novel design principles for DNA nanotechnology are presented here, from topological DNA nanostructures to complex and curved DNA nanostructures, from pure DNA nanostructures to hybrid RNA/DNA nanostructures. As one of the most important and pioneering fields in controlling the assembly of materials (both DNA and other materials) at the nanoscale, DNA nanotechnology is developing at a dramatic speed and as more and more construction approaches are invented, exciting advances will emerge in ways that we may or may not predict.
