We develop a strategy for the synthesis of multifunctional nanoparticles of mesoporous silica (Mag-Dye@MSN) that simultaneously possesses magnetic, luminescent, and mesoporous properties. These nanoparticles exhibit high T2 relaxivity and visible light emission. We further explore the potential of utilizing these multiple functionalities as dual-imaging probes for the labeling of biological cells and evaluate the cytotoxicity of Mag-Dye@MSN. These preliminary results demonstrate the potential of using these multifunctional nanoparticles for cell-labeling and integrated diagnosis applications.
