Plasma is a new medium that has remarkable properties in health care:
•
it is a broadband germicidal agent;
•
it inactivates bacteria, viruses, fungi and spores — ideal for hygiene;
•
it kills resistant bacteria in seconds;
•
it reduces the risk of infections;
•
it has regenerative properties — wounds heal faster;
•
it is cell selective — cancer cells are inactivated, healthy cells are
unaffected;
•
it soothes and heals many skin disorders;
•
there are no known detrimental side effects;
•
it even accelerates plant growth...
The big breakthrough for plasma medicine came with the development
of “Cold Atmospheric Plasmas”, which can be safely applied to human
skin and which have no known negative side effects.
The important current issues in plasma medicine are:
•
identify the processes that make plasma such a formidable germicidal
agent;
•
understand in detail the mode of action of plasma-cell interaction;
•
optimize plasma source and transport design for specific applications;
•
improve plasma chemistry for biological/medical applications;
•
investigate combined plasma-topical/systemic drug effects;
