Inductively heatable particle-based anti-microbial coating

Pathogens surround us omnipresent and are a major challenge to our daily lives not only since Covid 19. They can be transmitted through smear infections via contact surfaces such as door handles. The current state of the art in cleaning contaminated surfaces is treatment with liquid disinfectants, which comes with several disadvantages, such as a high cleaning effort, a large amount of waste and limitation to simple substrate geometries. To address all these challenges while reducing environmental impact, Fraunhofer ISC is developing antimicrobial coatings based on inexpensive, non-toxic inductively heatable magnetic particles. Due to their magnetic properties, the particles and their immediate surroundings can be inductively heated.  This enables fast and efficient cleaning of contaminated surfaces without the use of chemicals.

Claudia studied chemistry at Karlsruhe Institute of Technology KIT and joined the Fraunhofer Institute for Silicate Research in 2015 as PhD student. In her PhD in cooperation with the University of Würzburg she focused on redispersibility of nanoparticles from dry powders. From 2019, she was responsible for the topic particle-based coatings in the Particle Technology Division. Her expertise was the modification and combination of different particles to create particles with new and unique properties. Since the beginning of 2022, she has been a scientific leader in the Chemical Coatings Group at Fraunhofer ISC. Her research focuses in particular on the combination of coatings and particles. By introducing particles of different sizes and shapes, the coating properties can be extended and completely new areas of application emerge. Claudia is highly interested in interfacial phenomena that play a role in the integration of particles into different matrices.
