Metal–organic framework (MOF) nanoparticles and their assembly into three-dimensional superstructures are attracting attention in various fields. Now, a general spray-drying method has been developed to create more complex hollow spherical MOF superstructures and entrap guest species within them, thereby providing new routes to capsules, reactors and composite materials.
