▎ 摘　　要

NOVELTY - Ink comprises (i) a carrier, (ii) graphene and/or graphene oxide particles dispersed in the carrier, and (iii) a viral active and/or anti-microbial component adhered to the graphene and/or graphene oxide particles. USE - The ink is useful for providing a viral active and/or anti-microbial coating to a substrate or producing product. The composition is used as an anti-viral or viricide for severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2) (all claimed). The ink is also used for treating diseases caused by virus. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a viral active and/or anti-microbial product comprising a substrate, and a coating provided on the substrate, where the coating comprises (i) graphene and/or graphene oxide particles and (ii) a viral active and/or anti-microbial component adhered to the graphene and/or graphene oxide particles; (2) a face mask comprising the product; (3) a method of producing an ink involves (a) combining graphene and/or graphene oxide particles with a viral active and/or anti- microbial component to adhere the viral active and/or anti-microbial component to the graphene and/or graphene oxide particles, and (b) dispersing the combined graphene and/or graphene oxide particles and viral active and/or anti-microbial component in a carrier; and (4) a composition comprising functionalized graphene and/or graphene oxide particles, and a viral active and/or anti-microbial component adhered to the functionalized graphene and/or graphene oxide particles, where the viral active and/or anti-microbial component comprises capped metal nanoparticles.
