Disclosed are methods (100) for detecting an antimicrobial surface coating on a substrate (300) including the steps of applying (106) an anionic agent to a surface of the substrate (300), allowing (108) the anionic agent to bond to antimicrobial surface coating present on the substrate (300), removing (110) unbonded anionic agent, subjecting (112) the surface of the substrate (300) to a predetermined process to effect a change in the bonded anionic agent, observing (114) the change, and verifying (116), based on the observed change, the presence of antimicrobial surface coating on the substrate (300). The anionic agent may be an anionic thermochromic dye showing a visually detectable color change upon application of heat, or an anionic voltage-sensitive dye showing a change in spectral property upon application of a voltage, or an anionic fluorophoric dye showing fluorescence upon irradiation with UV light. Further disclosed are antimicrobial surface coating solutions, methods for their application, and methods for reactivated antimicrobial surface coatings.
本发明公开了用于检测基底(300)上抗微
