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.



  • We are happy to welcome Huanhuan Zhou, who has taken the long journey from China to support us in our scientific work as PhD student from now on. Her work will focus on the development of ID and recorder supraparticles. Welcome, Huanhuan.

  • Magnetic materials are always black! Really? Not necessarily: together with the group of Klaus Müller-Buschbaum we demonstrate that it is possible to design an all white magnet, based on a complex supraparticle. Read about it in J. Mater. Chem. C where our article was just accepted (https://pubs.rsc...

  • Congratulations to Sarah, Tim, Johannes and Susanne: Their article on "Abrasion indicators for smart surfaces based on a luminescence turn-on effect in supraparticles" was just accepted in the new journal of Wiley`s "Advanced" series: Advanced Phontonics Research!

  • Max Buchner Research Foundation founded by DECHEMA awarded one of this year’s scholarships to Susanne for the project “Creation of Janus particles via spray-drying” running from 01.07.2020 until 30.06.2021. Furthermore Susanne is one of the year 2020 scholarship-holders of Christiane Nüsslein-Volhar...

  • Jakob  received a doctoral scholarship from The German Federal Environmental Foundation (DBU) for his planed PhD work where he tries to develop recorder supraparticles for monitoring harmful environmental triggers as a key component for a more sustainable circular economy also for complex products l...

  • We are happy to welcome a new member to our working group. From now on Dr. Rosa Pujales-Paradela will support us in our scientific work as postdoc. Welcome, Rosa.

  • We have arrived safe and sound in beautiful Erlangen and are looking forward to an exciting time with new challenges at the Institute of Inorganic Chemistry at the FAU Erlangen-Nuremberg. However before we can continue with our research we will first set up the lab.
