Claims18
An ink for providing a viral active and/or anti-microbial coating to a substrate, comprising:
- a carrier;
- graphene and/or graphene oxide particles dispersed in the carrier;
- and
- a viral active and/or anti-microbial component adhered to the graphene and/or graphene oxide particles,
- wherein the viral active and/or anti-microbial component comprises metal nanoparticles capped with a capping agent;
- and
- wherein the graphene and/or graphene oxide particles and viral active and/or anti-microbial component combined have a weight content of 1 wt % to 5 wt % of metal nanoparticles.
