  • Publication number: 20240077417
    Abstract: The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.

  • Publication number: 20240075138
    Abstract: This disclosure provides isolated or recombinant polypeptides that are useful to vaccinate individuals suffering from chronic/recurrent biofilm disease or as a therapeutic for those with an existing infection. The individual's immune system will then naturally generate antibodies which prevent or clear these bacteria from the host by interfering with the construction and or maintenance of a functional protective biofilm. Alternatively, antibodies to the polypeptides can be administered to treat or prevent infection. Bacteria that are released from the biofilm by our technology are more readily cleared by the remainder of the host's immune system.
