Abstract: A multimode gas sensor platform can comprise an array of electrode pairs oriented on a substrate and a plurality of detection zones, wherein at least a portion of individual electrode pairs are separately addressable. Each detection zone can comprise at least one set of individual electrode pairs within the array, where the individual electrode pairs have organic nanofibers uniformly deposited thereon. The organic nanofibers can be responsive to association with a corresponding target material and at least one detection zone can be electronically responsive to the corresponding target material.

Abstract: A nanofiber composite sensor for detecting alkanes can include a network of contacting nanofibers having multiple contact points. Each contact point can form an interfiber interface of interdigitated alkyl chains. Alkanes can be adsorbed at the interfiber interface which results in an increased interfiber distance between first and second nanofibers and a decreased charge transfer efficiency. The detected alkanes can be in a vapor or liquid phase.
