A solution for controlling mildew in a cultivated area is described. The solution can include a set of ultraviolet sources that are configured to emit ultraviolet and/or blue-ultraviolet radiation to harm mildew present on a plant or ground surface. A set of sensors can be utilized to acquire plant data for at least one plant surface of a plant, which can be processed to determine a presence of mildew on the at least one plant surface. Additional features can be included to further affect the growth environment for the plant. A feedback process can be implemented to improve one or more aspects of the growth environment.

A blood processing apparatus including a blood supply unit, a centrifuge, a light irradiation unit, a filtering device, and a blood collection unit, which is characterized in that blood is introduced into the centrifuge and centrifuged, the centrifuged blood is passed through a transparent tube provided in the light irradiation unit while being irradiated with light applied, from the outside of the transparent tube, by a light irradiation device configured to include an infrared lamp with a wavelength of 830?5 nm, a red light-emitting diode (LED) lamp with a wavelength of 635?6 nm, a blue LED lamp with a wavelength of 420?5 nm, a green LED lamp with a wavelength of 530?5 nm, a yellow LED lamp with a wavelength of 585?5 nm, and ultraviolet (UV) lamps, and the blood irradiated with the light is filtered using the filtering device and collected in the blood collection unit.

A method, system, and apparatus for providing sterilization, decontamination, and therapeutic treatment may be provided. These may include a misting, vaporizing, spraying, foaming or other dispensing apparatus to cover a person, a surface, and enclosure, a room or other structure with an antimicrobial solution. Radiation sources, such as lights, may be utilized to expose the antimicrobial solution to a certain wavelength of radiation. The combination of the antimicrobial solution and the certain wavelength of radiation may create a synergistic reaction that causes an effect greater than the radiation or solution separately. A container or passageway including an apparatus dispensing a solution so that an object or person is saturated with an antimicrobial solution. The person or object is then exposed to a certain wavelength of radiation that creates a synergistic reaction between the solution and the radiation.

A method and a system for producing a change in a medium. The method places in a vicinity of the medium at least one energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.

Methods and systems for treating a biological fluid with light are disclosed. The methods and systems include determining the light dose being delivered to a biological fluid and adjusting the duration of a treatment or the intensity of light emitted in the event of a detected light source outage.

A method of disinfection of a surface of a subject of harmful microorganisms including pathogenic bacteria and viruses upon visible light irradiation using a genetically hybridized fluorescent silk is provided. The method includes placing a predetermined quantity of the genetically hybridized fluorescent silk i) directly on to a skin surface of a subject; or ii) on a medium and then placing the medium on the skin surface of the subject. The method further includes applying light in the visible spectrum for a predetermined amount of time to the placed quantity of genetically hybridized fluorescent silk.

A photoelectric device is disclosed. The photoelectric device includes a first electrode, a second electrode, and an electrolyte disposed between the first electrode and the second electrode. The second electrode includes a transparent layer for allowing light to penetrate into the second electrode, an electron transport layer coupled to the transparent layer, and a genetically hybridized fluorescent silk layer as a photo-sensitizer coupled to the electron transport layer.
