Abstract
The present invention relates to a method for killing cells characterized by bringing a material containing living cells into contact with a non-conductor-carrying photosemiconductor material or a cytocidal material containing the photo semiconductor material and killing the living cells by irradiating light onto the non-conductor-carrying photosemiconductor material, and to a cytocidal agent comprising non-conductor-carrying photosemiconductor material. This non-conductor-carrying photosemiconductor material is relatively inexpensive, since it does not carry a conductor and may be used safely for sterilizing drinking water, food, the human body, and the like because it does not release any poisonous metal ions derived from the conductor in use.
Claims5
A method of killing cells comprising the steps of placing living cells in contact with a non-conductor carrying photosemiconductor material and irradiating light to said non-conductor carrying photosemiconductor material to generate a photoelectromotive force, so as to kill said cells.
