Stable water suspension of core-shell La0.75Sr0.25MnO3@SiO2 nanoparticles is prepared in a sequence of the sol-gel procedure, thermal and mechanical treatments, the silica encapsulation employing tetraethoxysilane and final size fractionation by the centrifugation. Rat mesenchymal stem cells (rMSCs) are used for the in-vitro experiments carried out under frequency 480 kHz and amplitude 8.7 kAm-1. The aim is to distinguish two types of heating namely extracellular by nanoparticles surrounding the cells and intracellular by internalized nanoparticles.
