摘要： Methods for making disinfecting compositions based on phototherapy, systems for use in disinfecting with a combination of photosensitizers, and the disinfecting compositions themselves, are described. Concentrations of the photosensitizers can be based on the particular light source and the wavebands or fluence rates emitted by the light source for maximum singlet oxygen generation. Concentrations of the photosensitizers can also be based on the quantum yield of the photosensitizers.

摘要： An apparatus for vaccine generation includes a syringe with a cavity that includes a solution with photosensitizers. Microbial particles are added to the solution. A light source is capable of emitting one or more wavebands of light that are effectively absorbed by the one photosensitizers to generate singlet oxygen in the solution and other radical species that rapidly react with and damage lipids, proteins, DNA, and RNA of the microbial particles. This damage produces immunogens that can be applied as a vaccine to viruses and other infectious microbial particles. A plunger that fits within a proximal opening in the syringe is used for forcing the solution including the immunogens through the filter and out of the syringe while the photosensitizers, debris and unwanted microbial particles are trapped within the filter.

摘要： An antimicrobial preventive netting is disclosed that includes one or more photosensitizers that are capable of generating a cloud of singlet oxygen on each surface and openings through the netting in response to incident light. A depth of the singlet oxygen cloud may be less than 0.7 centimeters from a netting surface. The netting may be supported by screens, enclosures or headgear. The netting can be made by dipping or soaking the netting in a solution of one or more photosensitizers.

摘要： 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.

摘要： Antimicrobial films for generating singlet oxygen and their use is described. The antimicrobial films are generally thin films having two surfaces or faces. The first surface of the film is adhesive. Various adhesives, including, electrostatic charges, are possible. The second surface faces in a direction opposite from the first surface. The second surface of the film emits singlet oxygen when activated by light or ultrasound. Various photosensitizers can be incorporated onto the second surface of the films for generating the singlet oxygen. The singlet oxygen and other radical species generated from the antimicrobial films diffuses out from and in proximity to the films to form a layer or cloud of singlet oxygen at a concentration sufficient to inactivate microbial particles, e.g., viruses and other pathogens, that come within the singlet oxygen layer to provide a protective zone against microbial particles.
