Nanoelectronic capnometer adaptor including a nanoelectric sensor selectively sensitive to at least one gaseous constituent of exhaled breath

A capnometer;

• comprising:
• an airway adaptor having at least one channel configured for the passage of respiratory gas;
• at least one nanostructure sensor in fluid communication with the passage, the sensor configured to selectively respond to at least one gaseous constituent of exhaled breath comprising carbon dioxide;
• electronic hardware connected to the nanostructure sensor and configured to provide a signal indicative of a response of the sensor to the at least one gaseous constituent of exhaled breath;
• wherein the at least one nanostructure sensor comprises:
• a substrate;
• a first nanostructure over the substrate;
• at least two conducting elements in electrical communication with the first nanostructure;
• and at least one recognition material operatively associated with the first nanostructure, wherein the at least one recognition material comprises a material selected from the group consisting of benzylamine, naphthalenemethylamine, antracene amine, and pyrene amine.
