A general strategy to fabricate monodisperse hollow supraparticles is described by Zhiyong Tang and Yunsheng Xia on page 2585. Core/shell supraparticles are obtained using an in situ assembly method and subsequent selective oxidation of cores results in formation of monodisperse hollow supraparticles. This work highlights that the strategy of combining self-assembly with chemical reaction is promising to tailor both the structures and properties of hollow nanomaterials.
