  • Patent number: 10877021
    Abstract: A device for biological material detection includes a substrate; a through-hole through which a biological material to be tested passes, the through-hole being formed in the substrate; a molecule that interacts with the biological material to be tested passing through, the molecule being formed in the through-hole; a first chamber member that forms, with at least the surface including the through-hole on one surface side of the substrate, a first chamber to be filled with electrolyte; and a second chamber member that forms, with at least the surface including the through-hole on the other surface side of the substrate, a second chamber to be filled with electrolyte. The biological material to be tested is identified by the waveform of the ion current (passage time, shape, etc.) when the biological material to be tested passes through the through-hole.
