A fluorescent ruthenium (Ru) complex is coupled to magnetic Fe3O4 nanoparticles (NPs) via 3-(3,4-dihydroxyphenyl) propanoic acid (DHPPA) and O,O'-bis(2-aminopropyl) polypropylene glycol-block-polyethylene glycol-block-polypropylene glycol (PPG-PEG-PPG-diamine). The resultant Ru-Fe3O4 NP conjugate shows excellent colloidal, photochemical and magnetic stability, and is promising as a dual functional probe for biological imaging applications.
