Field-deployable antimicrobial product assemblies for air and water purification and methods of fabrication of the same

A field-deployable antimicrobial assembly designed for gases or liquids, the assembly comprising:

• a substrate,
• a first material in contact with at least one surface of said substrate,
• wherein said first material comprises nanotubes and/or nanopores,
• wherein said nanotubes and/or nanopores are open on one end only, and
• wherein said first material comprises at least one first antimicrobial material;
• and
• a second material deposited on at least a majority of surfaces of said nanotubes and/or nanopores,
• wherein said second material comprises at least one second antimicrobial material, and
• wherein said at least one first antimicrobial material and said at least one second antimicrobial material inactivate biological microorganisms in gases and liquids upon physical contact.

A method of forming a high surface area antimicrobial material, the method comprising:

• providing a substrate;
• forming a first material on top of or within said substrate,
• wherein said first material is formed by solution-based coating,
• wherein said first material comprises nanotubes and/or nanopores, and
• wherein said nanotubes and/or nanopores are open on one end only;
• and
• forming a second material,
• wherein said second material is disposed on a majority of surfaces of said nanotubes and/or nanopores,
• wherein said second material is formed by a vapor-phase coating process, and
• wherein said second material is antimicrobial, and
• wherein said second material inactivates biological microorganisms in gases and liquids upon physical contact.
