Plasma Technology: The Solution for Material-Specific Challenges

Plasma is sometimes referred to as a fourth state of matter. In fact, plasma is an excited state of a gas in which both radiation and reactive particles – such as radicals, ions, molecules, and free electrons – are generated. This diverse mix of particles can be used to coat, ablate, or chemically functionalize surfaces.

Our expertise covers both atmospheric pressure plasma and plasma-enhanced chemical vapor deposition (PECVD) at low pressures, enabling the precise introduction of chemical functionalities – such as carboxyl, methyl, fluorine, or amino groups – onto surfaces. These processes are particularly gentle, making them ideal for plastics and other sensitive materials.

In addition, we provide surface functionalization solutions for applications in in-vitro diagnostics and the biomedical field.

Thanks to plasma technology, we are independent of material, shape, or sample size. Plastics, metals, semiconductors, films, textiles, fibers, and powders can all be functionalized. We can also develop solutions for special requirements, such as functionalizing small cavities or heat-resistant surfaces.

Controlling Material Properties

Our coatings offer a wide range of possibilities for precisely controlling material properties. Our portfolio includes:

  • Anti-adhesion: Reduces the adhesion of substances to the surface.
  • Barrier coatings: Protects substrates from the penetration of moisture, gases, or other substances.
  • Adhesion promoters / intermediate layers / bonding: Improves adhesion between different materials or substrates.
  • Scratch protection: Shields the surface from wear and scratches.
  • Anti-fogging: Prevents surface fogging in humid environments.
  • Anti-ice coatings: Prevents ice from adhering to or forming on surfaces.
  • Friction reduction: Lowers friction between the coated surface and other materials.
  • Photocatalytic activity: Uses light energy to remove pollutants from the environment.
  • Sensor coatings: Optimize sensor performance and selectivity for specific analytes through tailored surface coatings.
  • Hydrophobing / hydrophilization: Adjusts surface wetting properties for specific applications.
  • Cleaning: Plasma can finely clean and activate a wide variety of sample surfaces.
  • Plasma-activated water: Plasma-treated water can, for example, break down pollutants or be used in medical applications.
  • Drug release: Enables controlled release of active ingredients from the coating.
  • Therapeutic coatings: Supports therapeutic effects directly at the surface.
  • Disinfection: Allows sterilization of sensitive samples.
  • Antimicrobial / antifouling: Inhibits microbial growth and prevents biofilm formation.
  • Biocompatible coating: Ensures compatibility with biological systems.
  • Enhanced cell adhesion: Specific functionalization promotes cell adhesion for biomedical applications.

Research Focus: PFAS

PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals widely used in everyday products. However, their persistence in the environment and potential health risks make them an urgent concern. Often called "forever chemicals," PFAS do not biodegrade and can accumulate in both ecosystems and the human body.

Our research focuses on detecting and reducing PFAS in the environment. Our goal is to develop solutions that minimize the health and ecological risks associated with these persistent chemicals.

Key Research Areas

Development of Optical and Electrical Sensors
We functionalize substrate components – such as particles, GFETs, or nanopores – to enable the sensitive detection of PFAS.

Nanopore Technology
We develop both functional and inert layers and can precisely tune pore diameters for specific applications.

In Vitro Diagnostics
We generate plasma-activated water (PAW) to study its effects on carcinoma cells and explore potential biomedical applications.
