Abstract
A bioactive coated substrate includes a base substrate, an indicator layer disposed over the base substrate, and a bioactive layer disposed on the indicator layer. Characteristically, the indicator layer has color sufficiently different from the bioactive layer to be visually perceived by a user when the bioactive layer wears away.
