Approval for Jun.-Prof. Golda's DAAD project

In collaboration with Dr. Claire Douat from the institute GREMI in Orléans, France, Jun.-Prof. Judith Golda has submitted a DAAD project on the diagnostics and application of plasma radiation as a CO source for sterilization in wound healing. This has now been approved by the DAAD for 1.1.2022.
The aim of the project is to investigate the production pathways and the role of the CO molecule in the plasma treatment of biological material. To study CO generation in CAPs, two well-characterized plasma sources will be used that have complementary operating principles: A radial kHz-dielectric barrier discharge with direct contact of the plasma including ions, electrons, and strong electric fields with the treated substrate; and a coplanar RF discharge where only the field-free plasma effluent containing reactive species and plasma-generated photons reaches the substrate. This project will explore possible synergistic effects between CO and plasma-generated species such as electric fields, ions and electrons, photons, and other neutral radicals. The two complementary plasma sources will be used to distinguish the effects of indirect and direct plasma treatment on the impact of plasma-produced CO on bacteria. The plasma sources used here will be characterized with CO2 admixture to ensure that the amount of CO produced is below the toxicity limit. Parameter variations will be used to determine the optimal CO production conditions.
The project includes travel expenses to address the planned research questions.
