title: Effects of atmospheric nonthermal plasma on invasion of colorectal cancer cells.
abstract: The effect that the gas content and plasma power of atmospheric, nonthermal plasma has on the invasion activity in colorectal cancer cells has been studied. Helium and helium plus oxygen plasmas were induced through a nozzle and operated with an ac power of less than 10 kV which exhibited a length of 2.5 cm and a diameter of 3-4 mm in ambient air. Treatment of cancer cells with the plasma jet resulted in a decrease in cell migrationinvasion with higher plasma intensity and the addition of oxygen to the He flow gas.
