A total transformation process fully decouples morphology and composition control in colloidal nanocrystal synthesis. In their Communication on page 8669 ff., R. E. Schaak et al. show how metal oxide nanocrystals can be transformed into chalcogenides of different metals using sequential anion and cation exchange reactions. The products retain the morphology of the starting material but contain entirely different constituent elements.
