Abstract

Through the different functionalities on Au nanosphere (AuNSs) and Au nanorod (AuNRs) surfaces, we successfully control AuNSs attachment onto either the end or side surface of anisotropic AuNRs via bio-recognition, and then consciously construct side-by-side or end-to-end assembly nanostructures. This study provides a feasible approach to organize nanoparticles with different morphologies into controllable assembly geometries, which can potentially benefit the construction of future nanodevices.

摘要

通过金纳米球（AuNSs）和金纳米棒（AuNRs）表面的不同功能，我们成功地通过生物识别控制 AuNSs 附着在各向异性 AuNRs 的末端或侧面，然后有意识地构建并排或端对端组装纳米结构。这项研究为将具有不同形态的纳米粒子组织成可控的组装几何形状提供了一种可行的方法，这可能有助于未来纳米器件的构建。
