Abstract
Apparatus for deactivating airborne biological organisms in a closed environment, including a fibrous substrate having one or more of non-conductive fibers and non-conductive yarns; elongated, substantially parallel electrodes disposed on or embedded in the fibrous substrate arranged as one or more pairs of adjacent electrodes, wherein a discharge gap is defined between each pair; a component configured for applying a voltage between each pair to generate a non-thermal microplasma in a corresponding discharge gap, wherein the non-thermal microplasma deactivates one or more biological organisms in air present within the closed environment; and a detector in communication with the apparatus.
