Controlled growth and shape-directed self-assembly of gold nanoarrows
Self-assembly of colloidal nanocrystals into complex superstructures offers notable opportunities to create functional devices and artificial materials with unusual properties. Anisotropic nanoparticles with nonspherical shapes, such as rods, plates, polyhedra, and multipods, enable the formation of a diverse range of ordered superlattices. However, the structural complexity and tunability of n...
متن کاملPhotonic interaction between quantum dots and gold nanoparticles in discrete nanostructures through DNA directed self-assembly.
Discrete nanostructures of CdSe@ZnS QDs and Au NPs were prepared and the photonic interactions between the QDs and Au NPs were systematically investigated. We found that the Au/QD ratio, separation distances between Au NPs and QDs, and the size of the Au NPs in a given discrete nanostructure all affect the interaction between Au NPs and QDs.
متن کاملDirected self-assembly of gold nanoparticles into plasmonic chains.
The plasmonic behavior of metals at the nanoscale is not only appealing for fundamental studies, but also very useful for the development of innovative photonic devices. The past few decades have witnessed great progress in colloidal synthesis of monodisperse metal nanoparticles with defined shapes. This has significantly fueled up the research of directing the metal nanoparticles to self-assem...
متن کاملTriangular Self-Assembly
We discuss the self-assembly system of triangular tiles instead of square tiles, in particular right triangular tiles and equilateral triangular tiles. We show that the triangular tile assembly system, either deterministic or non-deterministic, has the same power to the square tile assembly system in computation, which is Turing universal. By providing counter-examples, we show that the triangu...
متن کاملFacile and efficient preparation of anisotropic DNA-functionalized gold nanoparticles and their regioselective assembly.
Anisotropic nanoparticles can provide considerable opportunities for assembly of nanomaterials with unique structures and properties. However, most reported anisotropic nanoparticles are either difficult to prepare or to functionalize. Here we report a facile one-step solution-based method to prepare anisotropic DNA-functionalized gold nanoparticles (a-DNA-AuNP) with 96% yield and with high DNA...
