摘要：
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.
