The Program evolved over time from ceramics to the synthesis and functionalization of nanoparticles (NPs), followed by their assembly into complex materials. We will continue research on controlled material synthesis, particularly oxide materials with functional properties originating from their specific nanoscale structuring.
At the forefront are magnetic materials and their combinations with other materials assembled into multifunctional nanocomposites.
Special attention will be given to the synthesis of composite nanoparticles at interfaces, where a monolayer of NPs is assembled and surface chemical reactions occur only on one side. These reactions include surface functionalization, layer deposition, and bonding with other NPs. This approach enables the synthesis of Janus NPs with two distinct faces and different physical properties.
The development of plate-like Janus nanoparticles holds significant potential for breakthroughs in multifunctional nanohybrids with orientation-dependent physico-chemical properties. These materials are key for applications such as magnetically and electrically switchable optics, chemical sensors, wireless signal transfer, and contactless valves and pumps in microfluidics.
New bulk composites with periodically structured nanoparticles embedded in a transparent polymer matrix will be synthesized using magnetically directed assembly of colloidal magnetic NPs in monomers (e.g., MMA), followed by rapid polymerization. A novel method based on heating magnetic NPs in an AC magnetic field will be developed to ensure homogeneous polymerization.
In parallel with material synthesis, we develop knowledge related to applications. Proof-of-concept research on magneto-mechanical cancer treatment will be extended to new therapies for neurodegenerative and cardiovascular diseases. Using anisotropic magnetic NPs, we can disintegrate protein aggregates such as amyloid-β fibrils, a hallmark of Alzheimer’s disease, as well as assist drug delivery and disruption of blood clots.
In technology, we focus on magnetically mediated catalysis. A new method based on selective heating of catalysts in an AC magnetic field shows strong potential to improve catalytic selectivity, especially for thermolabile products. It also enables direct conversion of peak electrical power into chemicals (Power-to-Chemicals).
New magnetically recyclable catalysts will be developed, for example based on surface frustrated Lewis pairs on AlF₃ coatings, for use in the valorization of wood biomass.
