Abstract
Disclosed are methods for detecting an antimicrobial surface coating on a substrate including the steps of applying an anionic agent to a surface of the substrate, allowing the anionic agent to bond to antimicrobial surface coating present on the substrate, removing unbonded anionic agent, subjecting the surface of the substrate to a predetermined process to effect a change in the bonded anionic agent, observing the change, and verifying, based on the observed change, the presence of antimicrobial surface coating on the substrate. Further disclosed are antimicrobial surface coating solutions, methods for their application, and methods for reactivated antimicrobial surface coatings.
