Window with anti-bacterial and/or anti-fungal feature and method of making same
First Claim
1. An anti-bacterial window including an anti-bacterial coating supported by a glass substrate, the coating comprising:
- a layer comprising silver and/or copper;
at least one layer comprising a metal oxide on the glass substrate over at least the layer comprising silver and/or copper; and
wherein all layer(s) on the glass substrate over the layer comprising silver and/or copper are porous so as to permit silver and/or copper from the layer comprising silver and/or copper to migrate and/or diffuse to the outwardmost surface of the coating over time, said outermost surface of the coating also being a major surface of the window.

Abstract
Certain example embodiments of this invention relate to a window having anti-fungal/anti-bacterial properties and/or self-cleaning properties, and a method of making the same. In certain example embodiments, a silver based layer is be provided and the layer(s) located thereover (e.g., the zirconium oxide inclusive layer) are designed to permit silver particles to migrate/diffuse to the surface over time to kill bacteria/germs at the surface of the coated article thereby creating an anti-bacterial/anti-fungal effect. In certain example embodiments, silver may also or instead be mixed in with other material as the top layer of the anti-bacterial coating.
