Directed Self-Assembly of Gold-Tipped CdSe Nanorods

摘要

A primary challenge of the bottom-up approach to nanomaterials is the construction of complex architectures from the nanoscale building blocks.Self-assembly is the main paradigm to achieve this goal,where previous work focused primarily on spherical-shaped nanocrystals forming ordered monolayers,superlattices,and molecular-like dimers,trimers,and additional structures.Due to the spherical symmetry of the building blocks,there are no preferred orientations in such assemblies.
