Cerium oxide nanoparticles scavenge nitric oxide radical (˙NO)

Abstract

In this study we have obtained evidence that cerium oxide nanoparticles (CeO2 NPs) are able to scavenge nitric oxide radical. Surprisingly, this activity is present in CeO2 NPs with a lower level of cerium in the 3+ state (CeO2 NPs with low 3+/4+ ratio and therefore a reduced number of oxygen vacancies), in contrast to the superoxide scavenging properties which are correlated with an increased level of cerium in the 3+ state (CeO2 NPs with high 3+/4+ ratio and therefore an increased number of oxygen vacancies).
