Over the past 40 years, research in the fields of DNA nanotechnology and RNA nanotechnology has taken nucleic acid molecules out of their biological contexts and harnessed their unique base-pairing and self-assembly properties to generate well-defined, organized, and functional supramolecular architectures. Capitalizing on an intrinsic biocompatibility and the ability to tailor size, shape, and functionality from the bottom up, recent work has positioned high-order nucleic acid structures as powerful biomedical tools. This review summarizes advances in nanotechnology that have enabled the fabrication of synthetic nucleic acid structures. Nucleic acid-based platforms for biosensing and therapeutic drug delivery are highlighted. Finally, an outlook that considers the limitations and future challenges for this field is presented.
