Luminescence is used in cell imaging to unravel cellular processes, or in disease diagnosis. Some systems can be modified to add extra functionality, such as generating reactive oxygen species that are cytotoxic and can be used for treatment. Commonly used luminescent compounds such as organic dyes and nanoparticles have limitations from photobleaching, short emission lifetimes, excitation/emission bands outside of the biological window and cell damage due to high power excitation sources.
