Abstract
Systems and methods for the activation of species and/or the delivery of species to a target environment using harmonic generation materials are generally described.
Claims20
A method, comprising:
- exposing, to a harmonic generation material, electromagnetic radiation of a first frequency such that the harmonic generation material converts at least a portion of the electromagnetic radiation of the first frequency to electromagnetic radiation of a second, higher frequency, and the harmonic generation material releases the electromagnetic radiation of the second, higher frequency;
- wherein:
- the electromagnetic radiation of the second frequency is exposed to a material photosensitive to the electromagnetic radiation of the second frequency such that when the photosensitive material absorbs the electromagnetic radiation of the second frequency, the photosensitive material is physically and/or chemically altered;
- the closest distance between the harmonic generation material and the photosensitive material is less than about 1 centimeter;
- and
- the electromagnetic radiation of the first frequency has a wavelength less than or equal to about 2500 nm.
