Nano Structuring

Our Service

Ultrashort pulsed laser radiation can be used to produce precise nanostructures for functional surfaces. These high-precision, periodic surface structures can be selectively generated and manipulated by laser-induced surface effects or multi-beam interference.

The resulting nanostructures favor selective bacterial growth in biotechnology or the ingrowth behavior of ceramic implants in medical technology. Furthermore, multi-beam interference can be used to assemble complex security features from periodic surface structures with structure sizes in the range from 300 to 5000 nm and that have an individualized, characteristic spectral signature. These surface structures can be generated at surface rates of up to 60 cm²/min. In addition to the optical properties, the haptic and adhesive properties of components can be manipulated and adapted. Not only can these structures be used in medical technology and biotechnology, but they can also be applied in tool and mold making, the automotive, the aerospace and the electronics industries as well as in energy technology.

Fraunhofer ILT develops processes and builds system-technology components for the application-specific structuring of surfaces of different materials. The range of services includes market-oriented R&D services for nanostructuring, market and feasibility studies, tasks in the areas of design and simulation as well as comprehensive consulting.
