Plasma Bioengineering

The Plasma Bioengineering department bundles the competencies in the procedural development of processes that are based on the interaction of plasma with biological material. To this end, competencies are maintained in the development, coordination and diagnostics of plasma sources that are optimized for the task, as well as in the diagnostics of the biological systems that are dealt with. In addition, the derivation and optimization of the required process development is another focus area.

Current thematic focus areas are development of plasma processes for hygienization in the post-harvest area with an emphasis on the food sector, as well as innovative methods for process analysis and process monitoring.

Examples of the current activities of Plasma Bioengineering Department include

  • Development of a hygienization procedure based on reactive nitrogen species (RNS) that enables dry treatment, as well as wet treatment with one basic device.
  • Development of optical sensors for process monitoring based on special diode laser systems.

Application-oriented research work occurs predominantly on the basis of joint projects with considerable industry participation.
