Abstract
A gas sensor includes a biomaterial comprising electrically-conductive protein nanowires and at least two electrodes. The at least two electrodes are in operative arrangement with the protein nanowires and configured to provide a signal indicative of a change in conductivity of the protein nanowires. The conductivity of the protein nanowires is responsive to a change in concentration of a gas exposed to the biomaterial, such as ammonia, or to a change in relative humidity.
