Origami tomography
… on piecewise linear surfaces similar to folded origami. In contrast to the large number of projections usually necessary in traditional tomographic imaging, information is extracted directly from a small number of Radon projections. Furthermore, piecewise linear chains are shown to be fully …

Origami manifolds
An origami manifold is a manifold equipped with a closed 2-form which is symplectic everywhere except on a hypersurface, where it is a folded form whose kernel defines a circle fibration. In this thesis I explain how an origami manifold can be unfolded into a collection of symplectic pieces and …

Origami-inspired mechanical metamaterials
Origami-inspired mechanical metamaterials are recognised for their diverse property tuneability and controllable collapse behaviours, but their performances are often limited by the flat foldable unit cells. This thesis introduces a novel concept of heterogeneous origami-inspired mechanical …

Zero modes of origami-inspired trusses
… we turned to the fully 3D case of the Yoshimura origami pattern and related patterns, by considering the trusses formed by the pattern. For this case, we primarily applied numerical methods. This allowed easy visualization of its modes and modification of the pattern. The Yoshimura pattern …

Kinematic and dynamic modeling of Nanostructured Origami
Nanostructured Origami is a manufacturing process that folds nanopatterned thin films into a desired 3D shape. This process extends the properties of 3D design and connectivity found in origami artwork to the bulk fabrication of 3D nanostructures. Our technique is a two-step procedure that first …

Monte Carlo simulation of DNA origami self-assembly
The optimal design of DNA origami systems that assemble rapidly and robustly is hampered by the lack of a model capable of simulating the self-assembly process that is sufficiently detailed yet computationally tractable. In this thesis, we propose a model for DNA origami that strikes a balance …

Therapeutic applications of DNA origami-based programmable nanoparticles
DNA origami utilizes the complementary Watson and Crick base pairing of DNA to self-assemble highly programmable nanoparticles. These nanoparticles have distinct advantages over other nanoparticle delivery platforms, including polymeric and lipid nanoparticles, in that they offer precise nanoscale …
