Platform for the assembly of 3D hierarchically-organized nanomaterials

This technology is a platform to organize nanoscale objects into a 3D array using DNA programmable interactions, that can be used to generate 3D hierarchically ordered materials for optical and energy applications.

Unmet Need: Self-assembly of designed 3D nanoarchitecture

Advancements in lithographic and additive manufacture methods have supported tremendous progress in the field of small-scale manufacturing over the past few decades. However, current methods to generate specifically designed 3D nanomaterials on demand, with prescribed diverse structures and composition, are limited by a reliance on the composition and interaction of particles within these architectures and with the underlying organization.

The Technology: Platform for organized self-assembly of nanoparticles to form 3D nanomaterials

This technology describes a technique for organizing nanoscale objects into a 3D array using repeating mesoscale motifs and their elemental blocks—nanoscale voxels (defined units of 3D space that can be empty or occupied) with DNA-encoded directional bonds that can carry encoded nano-cargo, to target specific molecules to use during self-assembly. The technology permits the production of complex, hierarchical, and diverse 3D architectures while reducing the amount of information required to encode such complex structures. This technology provides a bottom-up method for fabricating 3D architectures from a variety of nanocomponents by design, for use in a variety of nanomaterial applications. This technology has been validated with x-ray scattering and electron microscopy approaches.
