Zusammenfassung:A method for indicating a sanitation status of a surface. The method comprises: contacting a coating on a surface with a cleaning composition, wherein the coating comprises a chromic material comprising core-shell nanoparticles which exhibit a clear baseline optical state under illumination with visible light prior to contact with the cleaning composition and an altered colored optical state under illumination with visible light after contact with the cleaning composition, the cleaning composition configured to induce a switch from the clear baseline optical state to the altered colored optical state; and illuminating the coating with visible light to reveal a sanitation status of the surface.
