Biomedical applications of gas plasma and natural pigments

Development of nonthermal plasma at atmospheric pressure has led to an expansion of biomedical applications in the past few decades. The fact that we are able to control ionization growth at high pressure and without vacuum enables direct exposure of cells and tissues togas plasma. Gas plasma is being used for wound healing, enhanced blood coagulation, sterilization of bacteria, cancer treatment, stem cell manipulation, etc. However, some of the most important challenges remain open. As the field of plasma medicine matures in clinical applications the questions of plasma selectivity, treatment doses, damage control, and efficient delivery of reactive species to cells and tissues require more attention
