General supraparticle formation: bridging molecular and materials chemistry
Upon droplet evaporation, using the tool spray-drying, forced assembly of nano building blocks to supraparticles is possible. Furthermore, via this method, also molecular precursors and molecules can be joined, i.e., we can also perform “chemistry in a droplet”.
We study how structure, besides composition, of such supraparticles affects the interaction among the building blocks of these entities and how this leads to unique functionalities.
