Abstract. The article analyzes the effect of different concentrations of GdYVO4:Eu3+ nanoparticles solution, which were pre-activated by ultraviolet light and not activated, on metabolic activity of the MCF-7 cancer cell culture. It was found that the degree of changes in the state of breast cancer cells depended on the concentration of nanoparticles, namely, the toxic effect was observed under conditions of exposure to high concentrations.
