Biological effect of zirconium dioxide-based nanoparticles

This work demonstrates the positive effects of zirconium dioxide nanoparticles on cells in vitro. This is supported by the absence of toxicity, stimulation of metabolic and proliferative activity. The nanoparticles of solid solution of europium oxide in europium dioxide do not exhibit an explicit biological effect. The potentially successful application of zirconium dioxide-based nanoparticles in pharmacology has been demonstrated.
