It is established that the pro- / antioxidant activity of such nanocrystals (NCs) is associated with the defect structure of NCs and the existence in their crystal lattice of ions with variable valence states that provokes a cascade of redox reactions under the interact of NCs with reactive oxygen species of different types. It is determined that the key role in the antioxidant activity of oxide NCs is played by the surface structure and the presence of oxygen vacancies. Prospective NCs from this point of view have been selected and the synthesis of test samples has been performed. The obtained samples were characterized by methods of electron microscopy, X-ray phase analysis, which allowed to obtain information about their crystal structure, size, etc.  Product Description popup.authors Yefimova Svitlana L.
