  • Publication number: 20240128480
    Abstract: An exemplary embodiment of the present disclosure provides a separator for a fuel cell, which is stacked on a reaction layer including a membrane electrode assembly (MEA). The separator includes a plate body stacked on the reaction layer, a wave pattern provided on one surface of the plate body that faces the reaction layer, the wave pattern being configured to define a reaction channel disposed between the reaction layer and the plate body and provided in a first direction in which a reactant gas is supplied, so that the reactant gas flows along the reaction channel, and a land provided along a lateral end of the wave pattern and disposed to be in contact with the reaction layer, thereby obtaining an advantageous effect of improving performance and operational efficiency.

  • Patent number: 8431337
    Abstract: There are provided a method and apparatus for detecting nucleic acid using bead and nanopore, and more specifically, a method and apparatus capable of detecting nucleic acid fragments of 70 bps to 300 bps in length by a nanopore detection unit with nanopores of 20 to 120 nm in diameter by attaching a bead to a nucleic acid probe and then detecting the bead attached to nucleic acid not nucleic acid itself. Accordingly, the present invention can detect the nucleic acid fragments using the nanopore detection unit with nanopores of 20 to 120 nm in diameter, even in case where Polymerase Chain Reaction (PCR) products are given as the sample, particularly the PCR products are the nucleic acid fragments of 70 to 300 bps in length.

  • Patent number: 7943369
    Abstract: A DNA (Deoxyribo Nucleic Acid) detection device and a manufacturing method thereof detects DNA by an electrical method without a separate process for detection by using semiconductor microfabrication techniques. The DNA detection device includes a pair of chambers formed on a semiconductor substrate for accommodating a detection sample, a channel connecting the pair of chambers and a lid covering the pair of chambers. According to the present invention, it is possible to attain a DNA detection device, which can be mass-produced from a silicon substrate by using semiconductor manufacturing technology with improved microfabrication techniques, and a manufacturing method thereof.

  • Publication number: 20090169431
    Abstract: Provided is a method of sensitively detecting nucleic acids in a nucleic acid sample, the method comprising: contacting the sample comprising the nucleic acid with a non-specific nucleic acid binding agent in an electrically conductive fluid medium; contacting the sample comprising the nucleic acid bound to the agent with a nanopore; and applying a voltage to the nanopore and monitoring a current change through the nanopore. The nucleic acid can be sensitively detected because a change in current amplitude through the nanopore is greater than when nucleic aid detection is performed without using an intercalator.
