Abstract
A substrate such as a woven or nonwoven fabric bound with a light-activated dye alone or in combination with additional conventional antimicrobial agents. The substrate is impregnated with a light-activated non-leachable dye having antimicrobial and/or antiviral characteristics which can be imparted to the substrate. The dye is bound by a cationic or anionic binder such as a water soluble polymer or carrageenan. Upon exposure to normal light, the dye generates singlet oxygen that kills microorganisms and viruses.
