Abstract
A device for detecting an airborne contaminant includes (a) a reactive polymer film having affinity for binding with the airborne contaminant, (b) an electrically conductive polymer film in contact with the reactive polymer film and having electrical property sensitive to binding of the airborne contaminant to the reactive polymer film, and (c) two electrodes in electrical contact with the electrically conductive polymer film for measuring the electrical property to detect the binding of the airborne contaminant to the reactive polymer film. Another device for detecting an airborne contaminant includes (a) a polymer film molecularly imprinted with the airborne contaminant, and (b) color reporting molecules having color sensitive to binding of the airborne contaminant to the polymer film. A method for manufacturing a device for detecting an airborne contaminant includes depositing, using one or more inkjet print heads, a polymer film and at least two electrodes onto a substrate.
