Synthesis of heterodimeric sphere–prism nanostructures via metastable gold supraspheres - Klajn, Rafal; Pinchuk, Anatoliy O.; Schatz, George C.; Grzybowski, Bartosz A. (Angewandte Chemie International Edition, 2007)
Changing shapes: Metastable spherical aggregates of gold nanoparticles undergo a one-to-one, thermally induced transformation into heterodimers comprising connected plate and spherical domains. By controlling the reaction time, it is possible to isolate a variety of structures differing in the relative sizes of the domains and in the overall optical properties (see picture).
