  • Patent number: 8642306
    Abstract: A liquid sample flow containing living cells is irradiated with measurement laser light and the photo data of at least either scattering light or fluorescence that is generated by each of the living cells in the liquid sample flow due to the irradiation with the measurement laser light is acquired. Based on the photo data thus acquired, it is determined whether each of the cells assignable to the respective photo data is an unnecessary living cell or a target living cell. Based on the determination results, a pulse voltage is then applied exclusively to the living cells having been determined as unnecessary living cells so that the unnecessary living cells are damaged and killed.
