A chemical sensor can include a nanofiber mass of p-type nanofibers having a HOMO level greater than−5.0 eV. Additionally, the chemical sensor can include oxygen in contact with the p-type nanofibers. Further, the chemical sensor can include a pair of electrodes in electrical contact across the nanofiber mass, where the p-type nanofibers conduct an electric current that decreases upon contact with an amine compound. |
