Our group demonstrated that DNA origami nanostructures with different structural designs exhibited different drug delivery functionalities. We investigated three nanostructures: Disc, Donut, and Sphere, and found that Donut was the most stable and showed the highest doxorubicin-loading capacity. The specificity of the uptake of these DNA nanostructures was enhanced by the Mucin1 aptamer modification; however, doxorubicin cytotoxicity in breast cancer cells appeared to be maximized in Donut when compared to other nanostructure, implicating that three-dimensional Donut proved to be the most efficient nanocarrier among the three designs.
