Abstract
Silver ions, while being lethal to single-celled microorganisms, are known to be harmless to human cells. We have adopted highly active fine organic silver grains, developed by combining our long accumulated fine organic synthesis and fine particle technologies, to the filter. Antibodies (also known as immunoglobulin) are used by the immune system to identify and neutralize foreign objects, such as viruses. For the antiviral function, we have applied the specific antibody ‘immunoglobulin yolk (IgY)’ for the filter, and the filter has proved to dramatically reduce the infectivity of type A (H1N1, H3N2) and type B influenza viruses and also of the Avian flu A(H5N1).
