  • Biodetector based on interference effect of thin film with ordered porous nanostructures and method for using same to detect biomolecules
    Patent number: 11448580
    Abstract: The present invention discloses a biodetector based on an interference effect of a thin film with ordered porous nanostructures. The biodetector includes a detection cell, a sensing unit disposed in the detection cell, and an optical fiber spectrometer for detecting reflectometric interference spectra of the sensing unit, wherein the sensing unit is an ordered porous thin film provided with three-dimensional ordered nanopores, and diameters of the nanopores are 20 nm-500 nm. The present invention further discloses a method for using the biodetector to detect biomolecules.
