• metabolism [15][16]. However, these free radicals can interact within biological systems, resulting in oxidative damage to the organism. These harmful effects can be counteracted by biological antioxidants, including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), the expression

• of which needs to be coordinately regulated with the onset of OS [17][18]. If this balance is interrupted, levels of NPs-activated OS surpass the capacity of the biological antioxidants, potentially resulting in toxic oxidative stress. As a result, central nervous system (CNS) dysfunctions might

Reported studies on nanoparticle-induced oxidative stress use different read-outs for radical production including fluorochromic assays [39], depletion of antioxidants [40], enzyme activity (e.g., catalase [41], superoxide dismutase), or oxidative DNA damage. For example, reactive oxygen species-mediated
