Abstract
Currently, magnetic/fluorescent composite materials are attracting a great deal of interest for the imaging modality in-vivo because they have many excellent features for luminescence phenomenon and magnetic response for external applied magnetic field. However, they have prepared by mixing magnetic particle and fluorescent particle. Therefore, it has problems such as increasing of particle size and shape. We succeeded in fabricating magnetofluorescent silicon nanoparticles including the magnetic components into the particles which can be controlled transport by external applied magnetic field. The magnetofluorescent silicon nanoparticles not only showed green fluorescence by controlling the particle size less than 3.0 nm but also provided efficacious biocompatibility.
