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 we can control structure upon supraparticle formation and how the obtained structure, besides composition, of such supraparticles affects the interaction among the building blocks of these entities and how this leads to unique functionalities.
