  • Molecule transferring device, auxiliary for molecule transferring device, and molecule transferring method
    Patent number: 7341864
    Abstract: A molecule introducing apparatus is provided with a power supply circuit 20 for supplying power, a step-up transformer 30 which is supplied with power from the power supply circuit 20 and which outputs a high voltage, a switching transistor 22 that blocks off and allows the supply of power from the power supply circuit 20 to the step-up transformer 30 and which generates an instantaneous high voltage, and a pair of electrode probes 50 for applying the instantaneous high voltage generated at the step-up transformer 30 to a predetermined region in a body. The molecule introducing apparatus oscillates DNA arranged outside a cell by the instantaneous high voltage so as to introduce the DNA into the cell.
