Abstract
PLA plasma sterilization of yeast fungus and spore-forming bacteria was performed using Ti and TiO2 target. The experimental results suggested that both the yeast fungus and spore-forming bacteria could be sterilized by plasma irradiation generated by pulsed laser ablation method. The effect using pure Ti target slightly stronger than that of the TiO2 target. This results suggests that the main sterilization factors were considered to be high energy metal atoms and/or ions in this system.
