Abstract: Studies of biological activity of cerium dioxide nanoparticles show that this compound exhibits antioxidant, antitumor, antibacterial and antiviral properties. The cerium dioxide nanoparticles were obtained by evaporation of a target by a pulsed electron beam in a low-pressure gas with a specific surface area of 190 m2/g. To determine the enzyme-like activity of cerium dioxide nanoparticles, chemical analysis of interaction with the hydrogen peroxide was carried out. The results show an active inhibition of reactive oxygen species at pH above 6.
Keywords: nanopowder, nanoparticles, suspension, cerium dioxide, reactive oxygen species, antioxidant.
