ANTIMICROBIAL COMPOSITIONS AND METHODS OF USING THEREOF

Disclosed herein are compositions (e.g., sprays, paints, etc.) that comprise antimicrobial zeolite nanoparticles. Also provided are hemostatic compositions comprising zeolite nanoparticles, dryer sheets comprising zeolite nanoparticles, and textiles comprising zeolite nanoparticles. Also disclosed are compositions (e.g., sprays) that include a binder polymer to improve coating adherence. In some cases, the zeolite nanoparticles can further comprise an optical tracer (e.g., a fluorophore) associated with the zeolite nanoparticles. The optical tracer can be interrogated to confirm presence of the zeolite nanoparticles (or a coating comprising the zeolite nanoparticles) on a surface. Also provided are methods of forming viricidal coatings using compositions that comprise zeolite nanoparticles dispersed in a carrier.
