Logo: The Supraparticle GroupWe assemble complex particles, so-called supraparticles, from nano building blocks, typically by means of ­spray‑drying; other methods are employed as well. The (mostly inorganic) nanoparticle building blocks are either tailored by means of wet chemical syntheses approaches by ourselves or are obtained from collaboration partners.

We are interested in novel, functional properties of such supraparticles to emerge from the cooperative interplay of the combined nano building blocks. We study how the supraparticle`s structure and complex composition determines the unique functionalities. With these supraparticles, we aim at creating smart materials in the field of sustainability; examples of applications include water purification, communicating materials and interactive surfaces.

Transfer to application is achieved together with the Fraunhofer part of our group at Fraunhofer ISC in Würzburg.



  • Agglomeration of magnetic nanoparticles in dispersion cannot only be controlled upon temperature change but this can also be measured in situ via magnetic particle spectroscopy!
    Great collaboration with the group of Tobias Kraus and the Fraunhofer IIS .

  • Spray-drying nanoparticles is not only interesting to create supraparticles. It is also a way to generate solid-filled aerosols. The process is a model to what happens when humans cough or sneeze virus particles such as SARS-CoV-2. Using harmless fluorescent silica-based virus analogues, it can easi...

  • Our artwork regarding our latest review article "Supraparticles for Sustainability" published in Advanced Functional Materials was chosen as frontispiece art.

  • we are pleased to welcome Andreas Wolf, a familiar face, to our group as a PhD candidate. His work will focus on interactive magnetic supraparticles, where magnetic markers are used to monitor the separation of battery active materials and additives.

    Welcome Andreas!

  • We are delighted to share that Dr. Rosa Pujales-Paradela, member of our group, has been recognized with the Outstanding Merit Doctoral Award for her thesis "Innovative Smart Probes for Molecular Imaging Applications" by the 2018-2019 Doctoral Awards Tribunal of the consortium Physics and Chemistry p...

  • We are happy to welcome a new member to our working group. From now on Thomas Zimmermann will be conducting his PhD at the Particle Technology Group at the Fraunhofer ISC in Würzburg. Welcome, Thomas.

  • The New Year 2021 starts with acceptance in Advanced Functional Materials of our new Review Article on "Supraparticles for Sustainability".
    In this Review Article, our group outlined the power of supraparticles to contribute to sustainability - including a definition of sustainability derived from ...
