Abstract
Disclosed herein are embodiments of a composition comprising at least three layers. Layers one and two each either comprises a sensitizer or an emitter, typically a metal ion or a dye, and the third layer may or may not comprise a sensitizer or emitter. Upon exposure to light, such as infrared light, the composition produces visible and/or UV light. The composition may further comprise a capping moiety, a therapeutic agent, an uptake enhancer, a detection moiety that binds to a desired target, a quenching moiety, or a combination thereof. The composition may be a particle, such as a nanoparticle, or it may be a planar composition. Also disclosed are embodiments of a method for using the composition, including, but not limited to, a method for delivering a therapeutic agent, or a method for detecting a target, such as a biological target.
