Effect of rare-earth-based nanoparticles on the erythrocyte osmotic adaptation
Rare-earth-based nanoparticles (REB NPs) have been employed in molecular and cell biology due to their unique features. However, their interaction with biosystems and the influence on cell functioning are poorly understood.
