cell environment or exert a photocytotoxic activity. The use of lipophilic ligands allows the corresponding ruthenium complexes to passively diffuse inside cells but limits their structural and photophysical properties. Moreover, this strategy does not provide any cell selectivity. This limitation is also faced by complexes anchored on cell-penetrating peptides. In order to provide a selective cell targeting

The present invention provides compounds suitable for functionalizing biomaterials, in particular prosthetics and implant materials, functionalized biomaterials, and methods for synthesizing the compound. The compounds contain an anchoring group, a group for covalent binding to modified osteoblast precursor cells and a group for binding to endothelial cells or precursor cells.
The design and synthesis of 18F-radiolabelled and fluorescent dual imaging agents allowing bimodal PET/FLI imaging is a current challenge. We report herein the development of a cyanine-based [18F]F-C-glycosyl dual imaging probe for fluorescence imaging (FLI) and a robust [18F]F–C bond for positron emission tomography (PET) imaging. Interestingly, the proposed strategy allows a late-stage coupling of
