An aqueous composition comprising chitosan and fibroin nanoparticles, with a diameter equal or lower than 140 nm, and an acid agent, with pH equal or lower than 6, and viscosity equal or lower than 3.5 kg×m.sup.−1×s.sup.−1 measured at 25.0±0.1° C., kit and method for finishing and/or preservation and/or restoration and/or renovation and/or repairing and/or consolidation of manufactures, in particular ancient manufactures are disclosed.

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.

A method of preparing a vinyl collagen microsphere polyamide fiber composite material includes the following steps: step 1: modifying a collagen with methacrylic anhydride to obtain a vinyl collagen, then emulsifying and cross-linking the vinyl collagen to obtain vinyl collagen microspheres; step 2: treating a polyamide fiber substrate with formaldehyde to obtain a hydroxylated polyamide fiber substrate, treating the hydroxylated polyamide fiber with (3-mercaptopropyl)trimethoxysilane (MPS) to obtain a sulfhydrylated polyamide fiber substrate; and step 3: modifying the sulfhydrylated polyamide fiber substrate with the vinyl collagen microspheres to obtain the vinyl collagen microsphere polyamide fiber composite material.

The invention is directed to a composite material comprising a biofabricated material and a secondary component. The secondary component may be a porous material, such as a sheet of paper, cellulose, or fabric that has been coated or otherwise contacted with the biofabricated material. The biofabricated material comprises a uniform network of crosslinked collagen fibrilsand provides strength, elasticity and an aesthetic appearance to the composite material.
