Abstract: Described herein is a 3D nanoscale building platform. The platform is based on cube-shaped DNA nanostructures that are rigid enough to preserve cubic shape. Different cubes are connected together through complementary overhangs. We have developed a computational design algorithm that finds the smallest number of different cube types required to self-assemble target 3D shape. Each cube can be functionalized by attaching a cargo inside of it or adjacent to it (e.g., gold nanoparticles, carbon nanotubes, proteins, etc.) and can thus be used as a “scaffold” to construct arbitrary shapes in 3D from individual nanoscale building blocks. The final assembly can be a 3D periodic lattice, or a finite-sized object. From our simulation-designed cubes, we export to an experimental blueprint, where the strands and interactions between them are designed to self-assemble into a target shape.

The computing device may send, to a second computing device and based on determining that the first command does not match the one or more change orders, an alert indicating the first keystroke log. In this way, unauthorized change to the computing system may be detected.
