This paper explores the development and organization of three-dimensional (3D) DNA nanostructures, focusing on the bulged triangle motif and its applications in assembling nanoparticles. The research highlights significant advancements in DNA nanotechnology, including the creation of pseudohexagonal arrays and new lattice designs. Key findings such as X-ray diffraction results demonstrate precise predictability of spacings and symmetry in complex DNA structures. This work sets the stage for future applications in nanomechanical devices and material organization.
