The invention relates to novel multi-modality probes for imaging, tracking and analyzing stem cells and related biological samples, and methods of preparation and use thereof. The molecular probes of the invention are constructed, for example, by utilizing (a) the high selectivity of long hydrocarbon chains for binding to plasma membranes of cells, (b) a near-infrared (NIR) dye for optical imaging, and (c) a radionuclide for PET or SPECT imaging. The in vitro and in vivo data of the optical and radiolabeled probes demonstrated their utility for detecting the presence of stem cells with multiple imaging modalities.
