The chemical concepts of bond strength and steric hindrance are extended to the nanoscale to control “reactions” of composite nanoparticles into primitive “nanomolecules” of well-defined shapes and sizes. The progress of these nanoscale transformations is controlled by an interplay between the strength of bonding between particles' reactive domains and the entropic effects because of the bulkiness of the unreactive parts.
