Methods and systems for producing a change in a medium. A first method and system (1) place in a vicinity of the medium at least one upconverter including a gas for plasma ignition, with the upconverter being configured, upon exposure to initiation energy, to generate light for emission into the medium, and (2) apply the initiation energy from an energy source including the first wavelength λ1 to the medium, wherein the emitted light directly or indirectly produces the change in the medium. A second method and system (1) place in a vicinity of the medium an agent receptive to microwave radiation or radiofrequency radiation, and (2) apply as an initiation energy the microwave radiation or radiofrequency radiation by which the agent directly or indirectly generates emitted light in the infrared, visible, or ultraviolet range to produce at least one of physical and biological changes in the medium.

摘要:
A system and method for light stimulation within a medium. The system has a reduced-voltage x-ray source configured to generate x-rays from a peak applied cathode voltage at or below 105 kVp, and a plurality of energy-emitting particles in the medium which, upon radiation from the x-ray source, radiate at a first lower energy than the x-ray source to interact with at least one photoactivatable agent in the medium. The method introduces the plurality of energy-emitting particles into the medium, radiates the energy-emitting particles in the medium with x-rays generated from a peak applied cathode voltage at or below 105 kVp; and emits a lower energy than the x-ray source to interact with the medium or with at least one photoactivatable agent in the medium.

摘要:
A system for energy upconversion and/or down conversion and a system for producing a photostimulated reaction in a medium. These systems include 1) a nanoparticle configured, upon exposure to a first wavelength λ1 of radiation, to generate a second wavelength λ2 of radiation having a higher energy than the first wavelength λ1 and 2) a metallic structure disposed in relation to the nanoparticle. A physical characteristic of the metallic structure is set to a value where a surface plasmon resonance in the metallic structure resonates at a frequency which provides a spectral overlap with either the first wavelength λ1 or the second wavelength λ2, or with both λ1 and λ2. The system for producing a photostimulated reaction in a medium includes a receptor disposed in the medium in proximity to the nanoparticle which, upon activation by the second wavelength λ2, generates the photostimulated reaction.

A system and a conversion element for power conversion. The power conversion system includes a power conversion device which produces electric power upon illumination and includes a light conversion device which down-converts and up-converts a radiant source of energy into a specific energy spectrum for the illumination of the power conversion device. The conversion element includes a first plurality of particles which upon radiation from a first radiation source radiate at a higher energy than the first radiation source, and includes a second plurality of particles which upon radiation from the first radiation source radiate at a lower energy than the first radiation source. At least one of the first plurality of particles and the second plurality of particles can be at least partially metal coated.
摘要:
Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength λ1, to generate a second wavelength λ2 of radiation having a higher energy than the first wavelength λ1. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.
