Methods are described and related devices, compositions, and systems, in which a caged compound is administered to a biological environment, the caged compound being caged with a long wavelength absorber, the long wavelength being a wavelength greater than or equal to 750 nm; and irradiating the biological environment to excite the long wavelength absorber with light at a wavelength in a range from 900-1100 nm, thus decaging the compound. |
