Functional surfaces through nanostructures

At nanoshape we developed a new technology to create functional surfaces without applying coatings or foreign materials. Instead, we modify the topography of the material surface creating specific nano- or microstructures while the base material remains unchanged. The modified topography leads to new functions such as reduced bacterial adhesion, improved fluid behaviour, or increased wear resistance.

How it works

To create a specific topography we use our proprietary, patent-protected technology that is based on hydrothermal oxidation. Hereby we modify the top layer of the surface - for example titanium or aluminum - under controlled temperature and pressure. The results are stable nano- or microstructures that emerge directly from the material itself and exhibit extraordinary physical, chemical and/or biological properties.

Unlike laser or other structuring methods nanoshape is a diffusion-based process that enables industrial batch processing and ensures a uniform surface even on complex geometries or parts with existing microstructures like SLA-implants.

By tuning process parameters we can create specific topographies tailored to different functional requirements - from superhydrophilic properties to bacteria repelling effects.

Key surface properties

Inspired by nature

Nature demonstrates that surface topography alone can create remarkable functionalities: from the water-repellent lotus leaf to the bacteria-repellent wings of a dragonfly. These effects emerge not from coatings or chemical treatments, but from the structure of the surface itself.

With nanoshape, we translate this principle into a robust, industry-ready technology: our process allows us to create defined nanostructures directly on technical and medical components, enabling new properties without replacing the base material or adding expensive materials. It's a simple yet powerful way to engineer surfaces with better functions – inspired by nature designed for real-world use.
