Three-dimensionally integrated micro-solution plasma (3D IMSP) generates a large number of microplasmas in contact with the aqueous solution flowing in a porous dielectric material. We have applied 3D IMSP to the sterilization of E. coli for the purpose of large-volume water sterilization. We have successfully sterilized the water (150 mL) with E. coli of 8x10⁶ cells/mL within 3 min. We also discuss the effects of plasma-treated water on the sterilization of E. coli.
