14. 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.
