Electrokinetic devices and methods are described with the purpose of propelling a dielectric fluid medium, usually air, and optionally collecting assayable agents from the medium. Electrokinetic flow may be induced by the use of plasma generation at high voltage electrodes and consequent transport of charged particles in an electric voltage gradient. The generation of electrokinetic flow has the disadvantage that certain amounts of ozone may be formed in the process. Methods and devices are described herein where suitable catalysts can be combined with the electrokinetic device in such a way that ozone is effectively destroyed in the effluent flow without compromising the amount of flow. |
