This study investigates the potential of a new multi-modal lanthanide chelate complex for specifically targeting brain tumor cells. We report here results from ongoing studies of up-take, sub-cellular localization and binding specificity of this new molecular imaging probe. Fluorescence microscopy investigations in living rat C6 glioma tumor cells demonstrate that the new imaging agent has affinity for glioma cells and binds to mitochondria.
