  • Patent number: 9289937
    Abstract: Provided are a filter fabrication method and the filter formed thereby. In this method, a three-dimensional graphene polymer complex filter can be easily fabricated. By forming various patterns at a surface of a collector, patterns can be simply formed at a surface of a filter. This provides advantages at control of pressure difference which can be one of the very important factors necessary for designing and fabricating a filter. Since the filter includes graphene particles homogeneously combined to the polymer nanofiber, the filter can represent a superior antibiosis.

  • Patent number: 9196946
    Abstract: A resonator includes a dielectric substrate, a conductor disposed over the dielectric substrate, and a high-dielectric pattern disposed between outer parts of the conductor. The conductor includes an arc part, which has a C shape, and the outer parts, which respectively extend outward from both ends of the arc part, such that the conductor has an omega shape as a whole. The high-dielectric pattern has a relative permittivity greater than a relative permittivity of the dielectric substrate. The resonator has a flat plate shape to increase a filling factor of a sample, thereby improving measurement sensitivity. Also, the resonator is miniaturized, and thus a biosensor system including the resonator is also miniaturized.
