Abstract
Photosensitizers are incorporated into articles, such a personal protective equipment. A method of applying continuous and consistent light includes fitting the articles with light sources and optical fibers to apply light to the areas of the articles incorporated with the photosensitizers. Photosensitizers can be applied to articles by various applicators in either a gel or solution. A gel can be particularly effective when used on hydrophobic surfaces. Photodynamic reactor systems can be used to determine the effective doses of photosensitizers and the light dosimetry which can then be applied for use with the articles.
