Welcome Laura! Continue

Advanced Functional Materials just accepted our work, in which we demonstrate for the first time the successful design of a true communicating particle which not only carries a unique ID but also a recorder functionality all in one entity. The full title is: “Communicating Particles: Identification ... Continue

Citrates are very often used to surface-functionalize iron oxide nanoparticles after their synthesis. However, they are not employed directly during synthesis as it is commonly observed that they inhibit the precipitation of the iron species. In our latest paper, which was just accepted by Particle ... Continue

We managed to create a single magnetic particle with over 77 billion encoding options. A breakthrough towards an all magnetic ID! The work can be found here. Continue

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! More detailed infromation can be found here.
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... Continue

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

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! Continue

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... Continue
