[Application of DNA origami in nanobiomedicine]

The development of DNA nanotechnology make it possible to artificially generate complex nucleic acid nanostructures with controllable sizes and shapes. DNA origami emerges as an effective and versatile approach to construct two- and three-dimensional programmable nanostructures, and represents a milestone in the development of structural DNA nanotechnology. Due to its high degree of controllable geometry, spatial addressability, easy chemical modification and good biocompatibility, DNA origami has great potentials for applications in many fields. In this review, we briefly summarize the applications of DNA origami in antigen-antibody interaction, targeted drug delivery and the synthesis of biomaterials.
