Plasmonic Janus particles produced via single-phase, template-free solution process

Innovative methods for particle formation, formulation and characterization

Development of tailored metallic, semiconducting or insulating particles using highly optimized bottom-up or top-down processes

Properties of particulate systems can be tailored for size, shape, morphology and surface, and their respective distributions. Tailoring the related formulation techniques (for example, stabilization, dispersion, suspension rheology, separation/classification, granulation) is inadequately understood but of utmost importance to particulate-based nanotechnology. The integration of the building blocks by tailoring their microscopic interactions into meso- and macro-scale structures defines to a large extent the multifunctional properties of the devices (product engineering). The following processes and technologies are developed:

  • New methods for shape- and size-controlled particle formation, including structured particles by spray pyrolysis for catalytic and photonic applications (the droplet as a microreactor), oxidation-stabilized metallic and non-oxide nanoparticles, shape control by template-based methods (for example, in ionic liquids, liquid crystalline phases and emulsions) and nano-milling
  • Scale-up and optimization of these methods
  • Separation and classification techniques for nanoparticles based on careful control of particle interactions
  • Tailoring structure formation processes by means of microscopic control of the particulate interfaces
  • In-line analysis techniques for particle size (e.g. SAXS) and particle interactions (e.g. non-linear optics)

For the cross-sectional Research Area A1 the Center for Functional Particle Systems (FPS) was established. The vision is to provide a ‘library’ of different types of particles with controlled size, shape, and internal morphology. Additionally, it is essential that the fabrication of the building blocks in sufficient quantities is possible, even under industrially relevant conditions. From these building blocks, multifunctional structures are assembled by innovative processes, providing the basis for new products with high added value for all four fields of application of EAM.


Logo of Interdisciplinary Center for Functional Particle Systems (FPS)The activities of Research Area A1 are organized in the “FPS” and moved in the FPS’s own new building in June 2012.

Aim of the Interdisciplinary Center for Functional Particle Systems (FPS) is to develop innovative methods and processes to generate, formulate and apply particles (building blocks) with tailored size, shape and structure as well as customized surface properties. The efficient generation of advanced multifunctional products with high value can however only be realized by interdisciplinary approaches. Based on the cross-sectional topic of particles, FPS brings together chemical engineering, materials science, chemistry, physiscs and medicine.
Developed from Research Area A1 FPS focuses on eight interdisciplinary fields of research: Particle formation, Interactions, Structure Formation, Applications, Modeling, Characterization, Processing, Life Science & Toxicology
