Abstract
Within the past 20 years, structural DNA nanotechnology has evolved from simple DNA tiles composed of a few strands to more advanced DNA origami nanostructures composed of dozens of unique strands. Meanwhile, the shape space of various RNA structures has also significantly expanded, and the tools for creating custom DNA and RNA nanostructures have been developed hand in hand with the ever‑increasing complexity of the designs. Recently, there has been increasing interest in hybrid RNA/DNA origami nanostructures, as the design paradigms created for DNA origami could also be adapted for RNA scaffold folding, thereby paving the way for programmable packaging of gene‑encoding RNA and its delivery, e.g., for the development of vaccines and therapeutics. In this insight, we briefly summarize the evolution of DNA and RNA nanostructures and focus on the recently reported hybrid RNA/DNA origami, their design principles/parameters, properties, and their potential use in gene delivery.
This review synthesizes the current design principles governing mRNA-DNA hybrid origami assembly, including helicity adjustment, crossover geometry and folding condition optimization, and examines the structural requirements for translational competence.
