Book excerpt: Plasma medicine uses non-equilibrium plasmas generated under atmospheric-pressure conditions. Therapeutical plasmas can stimulate tissue regeneration or inactivate cancer cells. This book reviews the interrelation between plasma chemistry and biochemistry complemented by discussion of the ways plasmas inactivate various pathogens. Focus is on the plasma effects on mammalian cells, subsequent consequences for cell-biological processes, and plasma applicability specific medical therapies. Contributions illustrate the ways cold atmospheric-pressure plasma can be used as a controllable source of redox-active species and as a useful tool for research in redox biology. Key Features Summarizes plasma chemistry, biochemistry, and microbiology Documents the ways plasmas interact with lipids, membranes, and cells Reviews therapeutic uses of plasmas in medicine Focuses on uses of plasmas as cancer treatment
