Patent ID: 7341864

Claim:
A molecule introducing apparatus, comprising: a voltage applying means, including: a plurality of electrodes placed close to each other in a gas, wherein the electrodes are adapted to generate an electric field around biological tissues or cells and exogenous molecules arranged outside the biological tissues or the cells via an insulation portion and wherein, from a single spike voltage, the electrodes are adapted to generate a non-porating electric field positioned around constituent molecules constituting a biological tissue or a cell for exciting a free resonance vibration of the constituent molecules and exogenous molecules arranged outside the biological tissue or the cell so as to cause reverberation between the constituent molecules and the exogenous molecules, the resonance vibration and the reverberation introducing the exogenous molecules into the biological tissue through a membrane of the biological tissue or into the cell through a membrane of the cell without poration of the membrane of the biological tissue or the cell; and a voltage generating means, including: a power supply means for supplying power; a voltage step-up means, which steps up voltage supplied from the power supply means and then supplies the voltage to the voltage applying means; a switching means, which blocks/allows the supply of power from the power supply means to the voltage set-up means to generate the single spike voltage to be supplied from the voltage step-up means to the voltage applying means; and a switching control means for controlling the switching of the switching means, wherein the single spike voltage consists of a single pulse.
