Molecular mechanics of DNA bricks: in situ structure, mechanical properties and ionic conductivity
… with subnanometer precision. In contrast to DNA origami, the DNA brick method permits a variety of different structures to be realized using the same library of DNA strands. As a consequence of their design, however, assembled DNA brick structure have fewer interhelical connections in comparison …

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 …

Unlocking precision medicine using DNA nanotechnology
… ligands are accurately positioned using DNA origami structures, multivalent interactions can be tuned to specifically bind to a single target, akin to aptamers or antibodies. I present the design and experimental validation of a DNA origami framework that can precisely tune the position of …
