Research Abstract |
Bio-imaging techniques to visualize specific cancer cells are important for diagnosis and medical treatments. Luminescent nano-materials with high biocompatibility, which can emit under excitation of visible light, are desired for the medical applications. In this study, luminescent Eu(III) doped hydroxyapatite nanocrystals were synthesized by a wet chemical method. A 3-aminopropyltriethoxysilane (APTES) molecule was immobilized on the surface, and then folic acid (FA), a specific cancer cell-binding molecule, was bonded to the amino groups of APTES. No differences of luminescent spectra were detected for the nanocrystals though the processes of immobilization of APTES and FA.
