Abstract
- Recently introduced DNA nanomolds allow the shape-controlled growth of metallic nanoparticles. Here we demonstrate that this approach can be used to fabricate longer linear metal nanostructures of controlled lengths and patterns. To this end, we establish a set of different interfaces that enable mold interactions with high affinity and specificity. These interfaces enable and control the modular assembly of mold monomers into larger mold superstructure with programmable dimension in which each mold monomer remains uniquely addressable. Preloading the molds with nanoparticle seeds subsequently allows the growth of linear gold nanostructures whose lengths are controlled by the DNA structure. Exploiting the addressability of individual mold monomers furthermore allows achievement of site-specific metallization, that is, to create defined metal patterns. We think that the introduced approach provides a useful basis to fabricate nanomaterials with complex shapes and material composition in a fully programmable and modular fashion.
