    摘要： A method and apparatus for a rapid disruption of cells or viruses using micro magnetic beads and a laser are provided. According to the method and apparatus for a rapid disruption of cells or viruses using micro magnetic beads and a laser, cell lysis within 40 seconds is possible, the apparatus can be miniaturized using a laser diode, a DNA purification step can be directly performed after a disruption of cells or viruses, and a solution containing DNA can be transferred to a subsequent step after cell debris and beads to which inhibitors of a subsequent reaction are attached are removed with an electromagnet. In addition, by means of the cell lysis chip, an evaporation problem is solved, vibrations can be efficiently transferred to cells through magnetic beads, a microfluidics problem on a rough surface is solved by hydrophobically treating the inner surface of the chip, and the cell lysis chip can be applied to LOC.

    摘要： Provided is a method of purifying nucleic acids using hydrogen bonding and an electric field, including: bringing a sample containing target nucleic acids into contact with an electrode coated with a material capable of forming hydrogen bonds with the target nucleic acids; applying a positive voltage to the electrode to move the target nucleic acids closer to the electrode so as to form hydrogen bonds with the material on the electrode; washing the electrode; and applying to the electrode a negative voltage to elute the bound target nucleic acids. According to the method, selectivity to nucleic acids and proteins increases due to hydrogen bonding, nucleic acid purification is possible within a short time through an electric field, and the bound nucleic acids can be efficiently eluted.
