Abstract
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.
Claims26
A chemical sensor, comprising:
- a) a nanofiber mass of p-type nanofibers, said nanofibers having a HOMO level greater than −5.0 eV;
- b) oxygen in contact with the p-type nanofibers;
- and
- c) a pair of electrodes in electrical association across the nanofiber mass;
- wherein the p-type nanofibers conduct an electric current that decreases upon contact with a amine compound.
2 more elements
A method of detecting trace amine compounds, comprising:
- a) contacting the amine compound with a nanofiber mass of p-type nanofiber, said nanofibers having a HOMO level greater than −5.0 eV;
- b) measuring a change in electric current associated with the nanofiber mass before and after contacting the nanofiber mass with the amine compound.
