With cold plasma, the permeability of the skin barrier for particles of specific size can be increased.
Particle sorption and modification
Plasma permeabilization
Human skin is particularly well suited for therapeutic treatment with cold atmospheric pressure plasma and, furthermore, offers advantages as a route for active-ingredient application.
Active-ingredient and particle sorption
Process parameters have been identified which allow the safe treatment of skin in order to improve the permeation of active ingredients and nanoparticles up to 200 nm, but which prevent the passage of larger particles and microorganisms.
