Claim 9:
10. A process for preparation of a nano-formulation for an antiviral coating emulsion, the process comprising steps of:
a. mixing a cross-linkable polymer, F-CQDs, and metal or metal oxide nanoparticles in double distilled water (DDW) to form an aqueous solution, wherein the metal or metal oxide nanoparticles are selected from the group consisting of AgNPs, CuNPs, CuONPs, and a combination thereof;
b. adding 20-50 μL of tetramethyl ethylenediamine (TEMED) and 20-50 μL of aqueous ammonium persulphate (5-15% w/v) to the aqueous solution of step (a);
c. dissolving an emulsifier (0.2-2% w/v) in an organic solvent;
d. mixing solutions of step (b) and (c) and ultrasonicating for 5-15 minutes to obtain a nanomaterial loaded hydrogel nano-formulation,
wherein the emulsifier is selected from the group consisting of Sorbitan monolaurate, Sorbitan monostearate, and Sorbitan monopalmitate, and
wherein the organic solvent is selected from the group consisting of n-hexane, n-heptane, and dichloromethane (DCM).
