Abstract

Injury is an everyday risk in our lives, but some of us could have several wound healing problems, originating from additional pathologies (diabetes, cancer, and vitamin defects). As a solution, some metal-based nanomaterials, such as cerium-oxide (CeO₂) could be applied, which could help the regeneration. The CeO₂ nanomaterials need to have antioxidant character in order to be used in wound healing. Besides the wide use of CeO₂ particles in the biological field, it could be also utilized as a catalyst. This study compares these two applications, analyzing the photocatalytic activity of differently shaped CeO₂ nanoparticles and their possible antioxidant character.
