Multiple polyalkylenimine antiviral film apparatus and method of use thereof

A method for reducing interaction of a set of a single virus type with a host, the set of the single virus type comprising a single virus member, comprising the steps of:

• forming a film from a solution comprising an at least partially protonated and at least partially deacylated poly(2-alkyl-2-oxazoline) and a first at least partially protonated polyalkylenimine, said film comprising a total cationic charge in a range of 0.001 to 10.0 coulombs per square inch, said total cationic charge countered with counteranions;
• inhibiting interaction of the single virus member, on said film, with the host through the steps of:
• electrostatically pulling together first multiple cationic sites of said first at least partially protonated polyalkylenimine to corresponding first multiple anionic sites of the single virus member;
• and
• electrostatically attracting second multiple cationic sites of said at least partially protonated and at least partially deacylated poly(2-alkyl-2-oxazoline) to corresponding second multiple anionic sites of the single virus member;
• and
• said step of inhibiting further comprising the step of:
• inactivating at least fifty percent of the set of the single virus type according to tests and procedures of ISO 21702 on a non-porous surface.
