Colloidal self-assembly has enormous potential as a bottom-up means of structure fabrication. Here we demonstrate hierarchical self-assembly of rationally designed charge-stabilised colloidal magnetic particles into ground state structures that are topologically equivalent to a snub cube and a snub dodecahedron, the only two chiral Archimedean solids, for size-selected clusters. These spherical structures open up in response to an external magnetic field and demonstrate controllable porosity. Such features are critical to their applications as functional materials.

Nanoscale is a high-impact international journal, publishing high-quality research across nanoscience and nanotechnology. Nanoscale publishes a full mix of research articles on experimental and theoretical work, including reviews, communications, and full papers. Highly interdisciplinary, Nanoscale appeals to scientists, researchers and professionals interested in nanoscience and nanotechnology, quantum materials and quantum technology, including the areas of physics, chemistry, biology, medicine, materials, energy/environment, information technology, detection science, healthcare and drug discovery, and electronics. For publication in Nanoscale, papers must report high-quality reproducible new work that will be of significant general interest to the journal's wide international readership. Nanoscale is a collaborative venture between the Royal Society of Chemistry Publishing and a leading nanoscience research centre, the National Center for Nanoscience and Technology (NCNST) in Beijing, China. image block The journal publishes weekly issues, complementing and building on the nano content already published across the Royal Society of Chemistry Publishing journal portfolio. Since its launch in late 2009, Nanoscale has established itself as a platform for high-quality, cross-community research that bridges the various disciplines involved with nanoscience and nanotechnology, publishing important research from leading international research groups.
