Abstract

Disclosed are methods for detecting a presence or absence of an antimicrobial surface coating including applying at least one detectable fluorophoric dye compound to a substrate, irradiating the surface of the substrate with ultraviolet radiation in the 100-415 nm wavelength range to excite the detectable fluorophoric dye compound, observing fluorescence of the excited fluorophoric dye compound, and determining the presence or absence of the antimicrobial surface coating based on the observed fluorescence. Further disclosed are antimicrobial surface coating solutions, methods for their application, and methods for confirming the presence and coverage of antimicrobial surface coatings.
