Abstract
The present invention describes the use of nanoparticle interfaces to chemically process solid nanomaterials into ones with tailorable core-void-shell architectures. The internal void sizes are proportional to the nanoparticle size, the shell thickness and composition, and can be either symmetric or asymmetric depending on the nature of the interface, each of which is controlled by the process of making.
