The SOD) can also react with hydroxyl radicals. This was former factor is responsible for activity of ceria nano confirmed in another publication [10] where the particles in biochemical processes, in particular, in inactivation of free radicals in a living cell, while the ability of 3–5 nm ceria nanoparticles present
