This study is aimed at finding the sterilization effect of electrostatic atomized water particles. We selected Serratia marcescens as a target bacteria,since it causes nosocomminal infections and opportunistic infections. We observed morphological changes of Serratia marcescens using a transmission electron microscope (TEM) after exposure to Electrostatic Atomized Water Particles.
 It was found that the electrostatic atomized water particles can inactivate Serratia marcescens at a high efficiency (98.7%) within 90 minutes. We observed that the outer membrane of Serratia marcescens is seriously damaged by the exposure to electrostatic atomized water particles for 90 minutes. Further study is needed to clarify what action of the electrostatic atomized water particles causes this morphological change in Serratia marcescens.
