Plasmonic assemblies of gold nanoparticles (AuNPs) triggered by DNA exhibited excellent biocompatibility and specific-targeting ability. Moreover, the integration of AuNPs and DNA allows the DNA scaffolds exhibit greater chemical stability and optical plasmonic properties. In this mini review, we summarized the development of DNA nanotechnology, especially DNA framework and DNA origami that were employed to fabricate two-dimensional and three-dimensional (3D) Au nanoassembled nanostructures.

In the past few decades, enormous efforts have been made to synthesize covalent polymer nano/microstructured materials with specific morphologies, due to the relationship between their structures and functions. Up to now, the formation of most of these structures often requires either templates or preorganization in order to construct a specific structure before, and then the subsequent removal of previous templates to form a desired structure, on account of the lack of “self-error-correcting” properties of reversible interactions in polymers. The above processes are time-consuming and tedious. A template-free, self-assembled strategy as a “bottom-up” route to fabricate well-defined nano/microstructures remains a challenge. Herein, we introduce the recent progress in template-free, self-assembled nano/microstructures formed by covalent two-dimensional (2D) polymers, such as polymer capsules, polymer films, polymer tubes and polymer rings.
