Semiconductor nanoparticles were synthesized by epitaxial growth of a GaN thin layer on magnetic sacrificial core consisting of ZnFe2O4 nanoparticles. Different quantities of nanoparticles were incubated in vitro with mesenchymal stem cells. High density of nanoparticles (50 µg/ml) leads to a decrease in the number of cells during incubation, while the density of nanoparticles as low as 10 µg/ml is enough to drag cells in culture and rearrange them according to the spatial distribution of the magnetic field intensity.
