Know-How Transfer: Plasma Medicine

Problem:

- Treatment of chronic wounds

- Diabetic patients often affected

Solution: - More than thousend patients clinically tested - Wounds successfully disinfected and healing boosted - No side effects observed

Approach: - Disinfection of wounds by cold plasma, new technology introduced by MPE - Plasma medicine as additional therapeutic tool


PLASMALAB chamber and 2 types of handheld plasma torches

Isbary et al. Brit. J. Dermatology (2010, 2012)

Plasma Treatment of Chronic Wounds - Clinical Studies

In an add-on therapy more than 3000 plasma treatments so far showed a highly significant higher germ reduction (independent of the bacterial species and level of resistance). There were no negative side effects. Wound healing seemed to be faster. Example: Patient No. 72


Know-How Transfer: Plasma Decontamination

Problem:

- Planetary protection: Avoid accidental contamination of other planets

- Need for sterilisation of sophisticated construction elements of spacecrafts

Solution: - Soft surface treatment with a plasma-designed reactive gas - First tests performed, effective reduction of bacteria and spores demonstrated

Approach: - Use cold atmospheric plasmas for sterilisation of spacecraft parts

Motivation:

- Quantum Test of Einstein‘s Equivalenvce Principle:

Universality of Free Fall tested by matter wave interferometry with BEC‘s of 2 atomic species (Rb/K)

- Explore unique properties of quantum matter: • coherence length • gravitational potential at small distances • lowest temperatures

Are inertial and gravitational mass really equivalent ?

Do all bodies fall equally ?
