Systems and methods for detecting antimicrobial surface coatings

A method, comprising:

• at least one of:
• measuring, by a conductivity measuring device, a conductivity of a surface of a substrate, or
• measuring, by a resistance measuring device, a resistance of the surface of the substrate;
• comparing, by the conductivity measuring device or the resistance measuring device, the measured conductivity or resistance, respectively, to a reference value;
• and
• determining, by the conductivity measuring device or the resistance measuring device, a presence or an absence of an antimicrobial system on the surface, wherein the antimicrobial system comprises a first coating, wherein the first coating comprises an antimicrobial compound, wherein the antimicrobial compound comprises a first end and a second end opposite the first end with a hydrocarbon chain therebetween, wherein the antimicrobial compound comprises a cationic functional group on the first end and a silane group on the second end.
