    Silica Encapsulated Manganese Perovskite Nanoparticles for Magnetically Induced Hyperthermia without the Risk of Overheating

  • Original language description

    Manganese perovskite nanoparticles of the composition La0.75Sr0.25MnO3 uniformly coated with silica were prepared by encapsulation of the magnetic cores (mean crystallite size 24 nm) using tetraethoxysilane followed by fractionation. Resulting hybrid particles form a stable suspension in aqueous environmentat at physiological pH and posses a narrow hydrodynamic size distribution. Both calorimetric heating experiments and hysteresis loops in the alternating field revealed high specific power losses, further enhanced by the encapsulation procedure in the case of the coated particles. The corresponding results are discussed on the basis of complex characterization of the particles and especially detailed magnetic measurements. Moreover the Curie temperature (335 K) of the selected magnetic cores resolves the risk of local overheating during hyperthermia treatment.
