摘要：
A method for sensing presence of at least one specified chemical component in a patient's sample gas, associated with a disease (or medical condition), and for associating presence of the disease with presence of the specified chemical component concentration in an identified concentration range. Pattern matching is applied to identify one or more specified components that are present in the sample gas. Measured electrical parameter values (EPVs) for each nanosensor are modeled by constitutive relations dependent on a polynomial of powers of component concentrations. The EPV models are used to estimate component concentrations for the differently functionalized nanosensors. Estimated concentrations are averaged over the sensors to provide an overall concentration value for each surviving specified component. These overall concentration values are compared with concentration ranges associated, to estimate presence or absence of a disease or medical condition.
