Abstract
A photosensitizer formulation can be disposed on or in a container. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation.
Claims20
An article, comprising:
- a substrate that is arranged within one or more portions of the article;
- and
- a photosensitizer formulation disposed on, or disposed in, the substrate along one or more dimensions of the substrate, wherein activation of the photosensitizer formulation generates singlet oxygen that causes damage to one or more of microbial or viral particles incident to an anterior surface of the substrate.
A fabric, comprising:
- a substrate that is arranged in a planar shape in one or more portions of the fabric;
- and
- a photosensitizer formulation disposed on, or disposed in, the substrate along one or more dimensions of the substrate, wherein activation of the photosensitizer formulation generates singlet oxygen that causes damage to one or more of microbial or viral particles incident to an anterior surface of the substrate.
The fabric of claim 12, wherein the fabric is further comprised of paper.
