Nanoparticle (NP)‐assembled microcapsules represent a new class of hollow‐sphere material, in which materials properties can be ‘programmed’ by way of NP and polymer compositions. Synthesis is based on a sequential self‐assembly of NPs and polymer macromolecules. Reported by Wong and co‐workers on p. 1145, this rapid, green synthesis technique applies to a wide spectrum of colloidal species and permits non‐destructive encapsulation of water‐soluble compounds. The inside cover shows a confocal microscopy image of water‐filled microcapsules composed of silica NPs and a fluorescence‐labelled polymer. The scale bar is 20 μm. The inset shows a simplified illustration of the microcapsule assembly process.
