1. A metal-infused, antimicrobial material, comprising:
a base substrate having a surface including a base substrate material selected from a group of materials consisting of a fabric, a textile, a foam, and a paper, the base substrate material including at least one organic compound that has a functional group;
a seed layer being chemically bonded to the base substrate and having a chemical structure including an ion of an antimicrobial metal that is chemically bonded to the functional group of the organic compound of the base substrate material via a coordinated covalent bond; and
a continuous bulk metal layer of a metal oxide or a metal hydroxide of the antimicrobial metal being chemically bonded to the seed layer and having a chemical structure including at least one molecule of the metal oxide or the metal hydroxide of the antimicrobial metal that is bonded to the ion of the antimicrobial metal in the seed layer via a metal-oxide ionic bond.
