The field of various phototriggered drug release and photoreactions, including reactions generally based on triplet-triplet energy transfer with light excitation at long wavelengths. Systems and methods for absorbing energy in a photosensitizer, and methods for making or using such systems, kits including such systems. The systems and methods comprise transferring that energy by triplet-triplet energy transfer to cleave a cleavable or other active moiety, for instance, in order to cause the release of a releasable moiety. In some cases, these may be contained within a suitable carrier material, for example, a particle or a micelle. Such systems and methods may be used in a variety of applications, including various biological or physical applications. For example, such systems and methods may be useful for delivering drugs or other releasable moieties to regions of a subject.
