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.
Claims26
A method, comprising:
- exposing, to a harmonic generation material, electromagnetic radiation of a first frequency and allowing the harmonic generation material to release electromagnetic radiation of a second, higher frequency;
- and
- exposing, to the electromagnetic radiation of the second frequency, 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.

A system, comprising:
- a harmonic generation material configured to convert at least a portion of electromagnetic radiation of a first frequency incident on the harmonic generation material to electromagnetic radiation of a second, higher frequency;
- a source configured to emit electromagnetic radiation of the first frequency such that the electromagnetic radiation of the first frequency is incident upon the harmonic generation material;
- and
- a photosensitive material configured to absorb the electromagnetic radiation of the second, higher frequency emitted by the harmonic generation material,
- wherein the photosensitive material is configured such that, when the photosensitive material absorbs the electromagnetic radiation of the second frequency, the photosensitive material is physically and/or chemically altered.
