  • Publication number: 20250085299
    Abstract: An immunoassay device for detecting blood type antigen-specific immunoglobulin, an immunoassay method for detecting blood type antigen-specific immunoglobulin, and a method for collecting blood type antigen-specific immunoglobulin are disclosed. The immunoassay device for detecting blood type antigen-specific immunoglobulin includes a substrate having a reaction space defined therein capable of receiving therein a detection target sample solution; a binding antibody positioned in the reaction space and immobilized on the substrate; a switching peptide having a peptide compound reversibly binding to a Fab region of the binding antibody and a fluorescent label binding to the peptide compound; and a fluorescence-quenching substance positioned adjacent to the fluorescent label and quenching fluorescence from the fluorescent label.

  • Publication number: 20230357990
    Abstract: Disclosed is a bioprotective composite material. The bioprotective composite material includes a fiber network support, a seed layer for covering a surface of the fiber network support, and pyroelectric nanostructures protruding from the seed layer. Such bioprotective composite material generates a pyro-potential by a temperature change, and thus, has improved antibacterial and antiviral activities.

  • Patent number: 7655902
    Abstract: This invention relates to a nanowire-assisted method for mass spectrometric analysis of a specimen. More specifically, by using nanowire which can fix a specimen and perform desorption/ionization of the specimen while effectively transferring laser energy to the specimen to be irradiated, thereby enabling to perform mass spectrometric analysis without using a matrix solution. This invention, by effectively performing desorption/ionization of a specimen using the above-mentioned nanowire, enables to effectively perform qualitative-, quantitative-, and micro-analyses of specimens as well as low molecular weighted specimens. Further, this invention enables to the typical device of mass spectrometric analysis used in MALDI-T of MS. In particular, this invention can perform mass spectrometric analysis of a specimen with molecular weight of less than 1,000 Da and perform quantitative analysis by fixing a specimen with a predetermined area.

  • Publication number: 20090261438
    Abstract: A semiconductor nanowire-based photosensor includes a substrate, at least a top surface of the substrate being formed of an insulator, two electrodes spaced at a predetermined interval apart from each other on the substrate, metal catalyst layers disposed respectively on the two electrodes, and visible-range semiconductor nanowires grown from the metal catalyst layers on the two electrodes. The semiconductor nanowires grown from one of the metal catalyst layers are in contact with the semiconductor nanowires grown from the other metal catalyst layer, while the semiconductor nanowires grown respectively from the metal catalyst layers on the two electrodes are floated between the two electrodes over the substrate.
