  • Publication number: 20230294026
    Abstract: A method of inactivating a virus that includes the step of contacting a virus with an antiviral composition comprising a hybrid antiviral metal-associated amyloid fibril comprising metal nanoparticles on a surface of an amyloid fibril to contact a virus and an antiviral composition comprising metal nanoparticles on a surface of an amyloid fibril wherein the antiviral composition removes virus and bacterial contaminants in water or air to non-detectable levels when water or air comes into contact with the antiviral composition.

  • Publication number: 20230050123
    Abstract: The present invention relates to novel composite materials comprising elemental gold in the form of single crystals, amyloid fibrils and a polymer. This composite material is similar to glassy plastics yet lighter than aluminum and has a golden shining similar to 18K gold. Due to its unique properties, this composite is termed “light gold”. This composite material suits, for example, watches, jewelry, radiation shielding, catalysis and electronics. The invention further provides for environmentally friendly methods to manufacture such composite materials.
