Stable water suspensions of core-shell La0.75Sr0.25MnO3@SiO2 nanoparticles were prepared in a sequence of the sol-gel procedure in the presence of citric acid and ethylene glycol, thermal and mechanical treatments, the silica encapsulation employing tetraethoxysilane and final size fractionation by the centrifugation. Rat mesenchymal stem cells (rMSCs) were used for the in-vitro experiments carried out under an alternating field in the range of 6.1 - 8.9 kAm-1 and frequency of 480 kHz. The aim was to distinguish two types of heating namely extracellular by nanoparticles surrounding the cells and intracellular by internalized nanoparticles.
