Abstract
A method for capturing airborne agents or products of agents, such as microorganisms, including viruses, and microbial antigens, toxins and allergens, comprising the formation of at least one curtain of charged particles in the form of an emulsion, a suspension or an aerosol, constantly renewing and regenerating said at least one curtain, and passing air containing airborne agents through said at least one curtain, which acting as a filter captures said agents; as well as a particle formulation for performing the method, comprising any charged particles dispersed in a liquid, including lipid-containing particles, e.g. in the form of an emulsion, or micelles, or lipid-containing particles in the form of an aerosol, or any other charged airborne particles in an aerosol.
