Plasma chemistry simulation of surface microdischarge in humid air for wound healing
Submitted for the GEC11 Meeting of The American Physical Society Plasma chemistry simulation of surface microdischarge in humid air for wound healing DAVID GRAVES, YUKINORI SAKIYAMA, MARAT ORAZOV, University of California at Berkeley, GREGOR MORFILL, Max Planck Institute for Extraterrestrial Physics Controlling fluxes of reactive oxygen species and reactive nitrogen species (RONS) created in humid air plasma is important for biomedical applications of surface micro discharges (SMD) We report results from a well mixed, dual zone model that couples a plasma region with a reactiontransport region, and incorporates about 50 charged and neutral species coupled through about 500 elementary reactions. Dominant species in dry air are O3, NO2, and N2O5, while HNO3 and H2O2 approach similar densities in humid air. Finally, we report initial results from coupling the plasma chemistry model to a transient, one dimensional wound healing model. Wound healing models, based on a reactiondiffusion description of cell dynamics, describe the spatial and temporal variations of chemo attractants, blood vessels, fibroblasts and the extracellular matrix.
