Main fields of work

Laser-based generation and characterization of nanoparticles in dispersed and conjugated form, such as colloids, aerosols, nano-composites and bio-conjugates, are the main focus areas of the Nanomaterials Group:  

• Emissionscharakterisierung (Aerosole, Gase) beim Laserschweißen und -trennen
• Generation of ultrapure, stable colloids through laser ablation in liquids
• Bio-active nanoparticle polymer composites (e.g. for implants)
• Bio-conjugation through in-situ functionalization of nano-particles (nano-targeting)

Current research activities and focuses

The Nanomaterials Group focuses on the generation and bio-conjugation of nanoparticles through laser ablation in liquids and investigates influences on the characteristics of colloids, such as dimensions, stability and surface converage:

• Nanoparticles junior researcher group within the "From regenerative biology to reconstructing therapy - REBIRTH" DFG Excellence Cluster
• Generation of nano-particle dispersion through ultrashort pulse lase ablation in organic solvents
• Generation of NiTi nano-particles and vaccination and coating using nanoparticles (within the scope of the C2 "micro-functionalized shape-memory alloys" sub-project as a part of the Transregio Special Research Field 37 of the German Research Foundation)

Integrating nano-particles in plastic materials without chemical precursors and within a single process step opens up new application fields that require high purities and homogenities, such as medical technology:

• C4 "nano-particle silicon-composite implants" sub-project within the scope of the Transregio 37 Special Research Field of the German Research Foundation.
• Joint project on "nano-functionalized polymer composites for bio-active medical implants (NANOKOMED) - sub-project "nano-polymer composites through laser ablation"
