The Supraparticle Group
Our research
In the Supraparticle Group, we design highly functional supraparticles, i.e., particles of a few µm in size that are composed of nanoparticle (and molecular) building blocks.
These complex entities are achieved via forced assembly of the (nano) building blocks, mainly by using the technique of spray-drying.
We study how structure, besides (multimaterial) composition, of such supraparticles affects the interaction among the building blocks of these entities and how this leads to unique functionalities.
We exploit these findings for designing highly innovative communicating / interactive supraparticles and multifunctional adsorber / carrier and catalyst entities.
Many different material systems are studied in the group, but a special focus is on iron oxide nanoparticle-based magnetic systems and their characterization in particularly via magnetic particle spectroscopy (MPS), a to date rather unexplored approach that we pioneer.

Transfer to real-life application is achieved together with the Fraunhofer part of our group at Fraunhofer ISC in Würzburg.
Ultimately, via smart supraparticles, we aim at contributing to sustainability.
Markus Heinlein completed his Master of Science degree this year in our group focusing on the relation of magnetic interactions within and between supraparticles.
Continuing with his research in the Supraparticle Group, he started his PhD thesis in November 2024 and will contribute to our efforts...
We say goodbye to Juanjo, who has been our colleague for the last couple months. He stayed in the Supraparticle Group as a visiting PhD student from Argentinia to study inductively heatable molecular switches based on co-doped ferrites and catechol derivatives coordination.
In a great collaboration with the team of Alan Lyons (City University of New York) and the colleagues from the Fraunhofer ISC, we demonstrate how to contribute to enhanced self-cleaning of glass, partly coated with dagger-shaped features from silica nanoparticles. The article was just accepted in So...
Congratulations Susanne and Karma Zuraiqi (RMIT) and who pulled this together, and Torben Daeneke, Ken Chiang, Julien Bachmann and Peter Wasserscheid who are co-CI's for this grant.
This mobility grant allows researchers from Germany and Australia to engage in an exchange of ideas regar...
Congratulations to Jakob for having successfully finished his PhD. Jakob did a fantastic job: his thesis on "Supraparticle designs for micrometer-sized information providers" was graded with summa cum laude!
At the first Battery Direct Recycling Conference held in Würzburg, Sara Li Deuso gave an insight into her research on magnetic supraparticles as identifiers in single-layer lithium-ion battery pouch cells. She received an award for the best poster - including a nice t-shirt!
