DETECTION OF ORGANIC PARTICLES, PARTICULARLY VIRUSES, WITH ENRICHMENT TECHNIQUE

摘要

Method of diagnosing organic particles, particularly virus, bacteria, fungus, and pollen, by concentration technique, wherein liquid or gas to be examined for determining the presence of said particles, if any, in body liquid is passed through a passage or labyrinth system and accumulated particles, if any, then are detected. A passage or labyrinth system is used for the concentration, having a permeability allowing the passage of said particles. The surface of the passage or labyrinth system and/or the surface of spheres or other bodies larger than the particles sought for, is prepared so as to bind said particles to said surface or surfaces, respectively, said particles at the passage of the liquid or gas through the passage or labyrinth system accumulating on the surface of such system directly, or indirectly bound to the spheres or other bodies. The accumulation of specific particles, e.g. virus, takes place only if the particles have bound to said surface or surfaces, respectively. If no formation of aggregates takes place, the virus particles and the latex spheres will pass through the passage or labyrinth system and thus will not be accumulated.
