  • Patent number: 8507258
    Abstract: A method of perforating a membrane and an apparatus therefor is presented. The method includes bringing a membrane-denaturing substance into contact with or close proximity to at least a site of the membrane, the substance inducing a membrane-denaturing reaction by a stimulus; providing the stimulus to the substance so as to denature the membrane; and perforating the membrane with a membrane-destroying member. The stimulus is carried through the membrane-destroying member. The present invention eliminates the influence of the membrane-denaturing agent on the substance to be injected into the cell. The present invention also enables applying the stimulus locally, with a simple construction.
