Luminomagnetic nanostructured Nd 3+ doped fluorapatite (FAP) coated Fe 3 O 4 nanoparticles were produced by hydrothermal method. X-ray diffraction analysis indicates that the prepared nanoparticles contain both FAP and Fe 3 O 4 phases. Electron microscope analysis shows the formation of nanoparticles of Fe 3 O 4 encased in rod shaped FAP nanoparticles of average length 40 nm. Magnetic measurements confirm the room temperature superparamagnetic nature of the nanoparticles with saturation magnetization value up to 7.8 emu/g. The prepared nanoparticles display strong near infrared (NIR) emission at 1060 nm under 800 nm excitation. Cell viability studies for 72 hour demonstrate the survival rate of over 84% with 500 μg/mL concentration indicating the good cytocompatibility of the prepared materials. The present Nd 3+ doped FAP coated Fe 3 O 4 nanostructure provides an excellent multifunctional platform for diagnostics and therapeutic applications.
