Gold nanoparticle incorporated cells.

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" 

Diplom-/Master-/Bachelor-theses offers

The LZH group Nanomaterials is a interdisciplinary working group of physicists, biologists, engineers and chemists who focus on generation of nanomaterials by laser ablation in liquids. By this manner nanoparticles of high purity and almost any materials are accessible.

Such nanoparticles are of high interest in versatile applications like medicine, material science or power, environmental and electrical engineering. With its excellent equipment of laser sources and analytical devices the LZH performs a manifold of projects within the areas of laser-generated nanoparticles, nanocomposites and bioconjugates.
