About this collection
Colloidal nanochemistry offers the possibility of synthesising nanostructured materials that exhibit novel and/or collective properties, and have capabilities that can be exploited in multiple applications. As such, the understanding of the formation of complex all-nanocrystal-made structures from their building blocks is essential for the design of hierarchically structured materials.
Guest edited by Professor Marie Paule Pileni (University Pierre & Marie Curie), Dr P. Davide Cozzoli (CNR Nano) and Professor Nicola Pinna (Humboldt-Universität zu Berlin), this themed issue focuses on novel approaches and strategies for the assembly and the hetero-structuring of colloidal nanocrystals.
