Antioxidant Activity of Ablated CeO2 Nanoparticles with Narrow-Size Distribution

A method for the synthesis of nanodispersed aqueous solutions based on ablated cerium dioxide nanoparticles with a narrow-size distribution has been developed, and their physicochemical properties have been investigated. The nanoparticle sizes of CeO2 were analyzed using atomic force microscopy and small-angle X-ray scattering. The dependence of the electronic structure of ablated cerium dioxide nanoparticles on their size was established. The influence of the size factor on the antioxidant properties of the obtained particle size groups was investigated.
