Cellular therapies hold great promise for the treatment of various diseases. Its success strongly depends on the imaging modality and cell tracking, which can be achieved by the addition of an imaging label to cells, for example in the form of nanoparticles. Here, we report on polymeric nanoparticles encapsulating perfluorocarbon and dye, which can be used for cell loading and can be detected with several imaging modalities. This will further give information about cell numbers and localization in vivo.
