A method of treating a viral infection, the method comprising administering a pharmaceutically effective amount of an active ingredient of a nano-perforator comprising a lipid bilayer nanodisc, a membrane scaffold protein surrounding an outer circumferential surface of the nanodisc, and a receptor for a surface antigen of a virus to a subject having a viral infection, wherein the nano-perforator excludes a nano-perforator comprising 1-palmitoyl-2-oleoyl-sn-glycero-3 [phospho-rac-(1-glycerol)] (POPG) lacking the receptor for the surface antigen of the virus.
