Bioactive nanocomposites based on cerium dioxide as promising materials for protection against oxidative stress and its consequences

According to the materials of report at the meeting of the Presidium of the NAS of Ukraine, December 17, 2025

Abstract

The report presents the results of comprehensive studies on two types of nanocomposites based on CeO2 nanoparticles (combined with activated carbon particles and magnetic Fe3O4 nanoparticles) exhibiting synergistically enhanced bioactivity compared to the individual components. Specifically, the studies demonstrated that the combination of different types of nanoparticles within a single composite, as well as the variation in synthesis conditions, allow for targeted control over the morphology and redox state of the nanoparticle surfaces, which directly influences their bioactivity. Based on comprehensive physicochemical and biological investigations, mechanisms of synergistic bioactivity enhancement through component interactions in the composites were proposed, highlighting their potential as an effective and promising tool for the development of multifunctional agents to combat oxidative stress and its consequences.
