Complex DNA Architectonics─Self-Assembly of Amphiphilic Oligonucleotides into Ribbons, Vesicles, and Asterosomes

Abstract: The precise arrangement of structural subunits is a key factor for the proper shape and function of natural and artificial supramolecular assemblies. In DNA nanotechnology, the geometrically well-defined double-stranded DNA scaffold serves as an element of spatial control for the precise arrangement of functional groups. Here, we describe the supramolecular assembly of chemically modified DNA hybrids into diverse types of architectures. An amphiphilic DNA duplex serves as the sole structural building element o… Show more

“…Using DNA nanotechnology, oligonucleotides with specific sequences can be designed to self-assemble into a variety of low-dimensional structures such as multi-armed junctions, dendrimers, hairpins, and loops . Much larger DNA structures with sizes on the order of hundreds of nanometers have also been realized through DNA origami, and similarly large vesicles, ribbons, and star-shaped structures have been self-assembled using chemically modified, amphiphilic duplex DNA where the ends are hydrophobic and the interior is hydrophilic. , In addition to having enormous structural diversity, DNA is amenable to a vast number of chemical modifications including dye labeling. By chemically attaching dyes to the DNA backbone, it is possible to bring dyes into close proximity at sub-nanometer separations.…”

“…containing hydrophobic (sticky) ends, has been shown to be a viable alternative for the formation of DNA-based nanostructures. [29][30][31][32][33][34][35] Recently, we reported the supramolecular self-assembly of 3′-end modified DNA conjugates into vesicles, using phenanthrene or tetraphenylethylene sticky ends. 36,37 The hydrophobic interactions between the aromatic overhangs are a key element for the self-assembly process.…”
