Abstract
A bioactive coated substrate includes a base substrate, an outermost bioactive layer disposed over the base substrate, and a topcoat layer disposed on the outermost bioactive layer. Characteristically, the topcoat layer defines a plurality of pinholes that expose the outermost bioactive layer. A method for forming the bioactive coated substrate is also provided.
