Application of chemical recognition layers to carbon nanotube field effect transistors (NTFET) can induce specificity to analytes of prime interest. In particular, employing pH sensitive polymer layers provides a facile route for the accurate detection of CO 2 gas. Coupling the scalable processes for NTFET device fabrication and sitespecific polymer deposition can provide an accessible method for producing thousands and even millions of tiny, robust gas sensors for airway monitoring.
