General supraparticle formation: bridging molecular and materials chemistry
We start from synthesizing inorganic nanoparticle building blocks by means of wet chemistry. Via control over the wet chemical synthesis parameters, the size, shape and composition of the nanoparticles, thus their physical properties (e.g. optical or magnetic or adsorber or catalytic properties), can be tailored. From collaboration partners, we obtain further inorganic or organic nano or molecular building blocks.
By means of spray-drying and other methods, we assemble the different building blocks to more complex entities, so-called supraparticles. We study how the assembly process can be influenced to tailor the supraparticles`s composition and structure as this determines the ultimate functional properties of the supraparticle systems.
