Microcapsules with multilayer‐thick shells are synthesized by depositing negatively charged nanoparticles around cationic polyamine aggregates crosslinked by multivalent counteranions (see Figure and inside cover). Unique among hollow‐sphere preparative routes, this rapid and green synthesis leads to a robust organic/inorganic hybrid structure, applies to a wide spectrum of colloidal species, and permits the non‐destructive encapsulation of water‐soluble compounds.
