Query: Cold Gas Plasma Sources and the Science behind their Applications in
  Biology and Medicine   Studies on the interaction of plasma generated at atmospheric pressure and at
room temperature (low temperature plasma or just cold plasma) with biological
cells and tissues have revealed that cold plasma has therapeutic effects that
form the basis for new medical therapies. Cold plasma exhibits bactericidal
properties and at low doses can modulate cell functions, including
proliferation, attachment, and migration. Research in the last two decades has
shown that cold plasma can be used for wound healing and can kill cancer cells
in a selective manner. This paper describes the fundamental science behind the
biomedical applications of cold plasma.
