ABSTRACT:
A method for collecting airborne particles and microorganisms by injecting them into a swirling air flow from where they are removed onto a dry surface, a surface coated with an adhesive material or a surface wetted by a liquid that is swirled onto that surface from a liquid reservoir below. The swirling air motion and the aerosol injection into it are achieved by pushing or drawing the airborne particles and microorganisms through one or more nozzles that are directed at an angle towards the collection surface.
