Abstract:
A composite laminar structure treated to inhibit micro-organisms from thriving thereupon, comprising a suitable thickness of two or more expanses of woven or non-woven materials. A plurality of nano-particles, including materials such as silver, are distributed relatively uniformly across and sufficiently durably coupled with the two or more material expanses to resist removal during normal use and mild laundering. The nano-particles possess anti-microbial properties suitable to substantially inhibit population growth of one or more micro-organisms. The laminar structure may be configured as an insole for a shoe, or as other articles for wear or use in other applications where growth of micro-organisms is undesirable.
