  • Publication number: 20210318290
    Abstract: Provided is a non-invasive method of detecting or screening for a cancer in a subject specimen originating in a tissue outside of the lung. The method includes detecting elevated levels of one or more carbonyl-containing volatile organic compounds (VOCs) that are biomarkers for the cancer in exhaled breath from the subject specimen. The method may further include obtaining exhaled breath from the subject specimen; forming adducts of the carbonyl-containing VOCs with a reactive chemical compound; quantifying the adducts of the carbonyl-containing VOCs to establish a subject value for each of the adducts; and comparing each subject value to a threshold healthy specimen value for each of the adducts of the carbonyl-containing VOCs. One or more subject values at quantities greater than threshold healthy specimen values are also useful for screening for the cancer in the subject specimen.

  • Patent number: 8663581
    Abstract: A chemical pre-concentrator is provided having a support structure, an airflow conduit, and a layer of a reactive chemical compound on a surface of the support structure is used for collecting and pre-concentrating at least one chemical analyte from a dilute sample. A method of concentrating a gaseous sample is provide that includes exposing the chemical pre-concentrator with a dilute gaseous sample that contains at least one chemical analyte; and forming a conjugate of the at least one chemical analyte. A method of diagnosing a disease state in a mammalian patient is provided using the chemical pre-concentrator.
