Abstract

A tensegrity strategy has been explored to construct a rigid geometrical structure (triangles) from flexible DNA four-arm junctions. The resulting DNA triangles could self-assemble into 1D and 2D arrays. This tensegrity strategy is expected to play an important role in the design of biomimetic nanomaterials.
