  • Patent number: 11921048
    Abstract: The present disclosure relates to a fine particle-trapping sensor including: a plasmonic hotspot layer formed of a first metal; and a trapping layer formed of a second material. The inventors of the present disclosure have made extensive research efforts to develop a more effective and novel sensor for the real-time and high-sensitivity detection of droplets emitted from the oral cavity. As a result, the inventors have developed an alloy composite nanostructure including a Raman sensor layer, formed of a metal, and a trapping layer formed of a dielectric material, and have found that, when the ratio between the two layers is adjusted, the alloy composite nanostructure effectively traps respiratory droplets rapidly emitted from the oral cavity and detects coronavirus (SARS-CoV-2 lysate) in the respiratory droplets at a concentration of 10 pfu/ml, indicating that the composite nanostructure may be very advantageously used in the field of fine particle trapping.

    Abstract: The present invention combines the advantages of fabrication of semiconductor heterostructure (Ag3PO4—WO3) with plasmonic metals (Pt and Ag) with optical interference to optimize the visible light photo response of plasmonic metals deposited semiconductor (Pt—Ag/Ag3PO4—WO3) for visible light assisted H2 generation utilizing the aqueous bio-alcohols. Crystalline Ag3PO4 and WO3 nanofibers were synthesized by microwave and electrospinning methods. Three different WO3 nanofibers composition (5, 10 and 15 wt. %) were used to obtain Ag3PO4/WO3 nanocomposite heterostructures, which are effective visible light active photo catalysts. Further, a simple, enviro-friendly, and cost-effective biogenic synthesis method have been achieved using Salvia officinalis extract to decorate Pt and Ag metal nanoparticles on the surface of Ag3PO4—WO3 composites. Presence of bioactive agents in the extract are responsible for the Pt and Ag3PO4 reduction and for prevention of the Pt nanoparticles from aggregation in aqueous medium.

  • Patent number: 11788957
    Abstract: Methods and systems for analyzing a sample and generating a predictive model using cavity ring-down spectroscopy are disclosed. At least part of a sample is loaded in a ring-down cavity. For each of a set of wavelengths, a laser beam is generated and directed into the ring-down cavity. The laser beam entering the ring-down cavity is extinguished. Light intensity decay data for light exiting the ring-down cavity is registered via a light intensity sensor system. A probability is determined from the light intensity decay data for the set of wavelengths that a subject from which the sample was received has a physiological condition or a degree of the physiological condition at least indirectly using a dataset of light intensity decay data for previously analyzed samples for which the presence or the absence of the physiological condition or the degree of the physiological condition have been identified.
