4486 1316 Magnetite nanoparticles-based hydroxyl radical scavenging activity assay of antioxidants using N, N-dimethyl-p-phenylenediamine probe https://doi.org/10.3906/kim-2006-9 Metal oxide Magnetite nanoparticles (Fe3 O4 :MNPs) have attracted attention because of their peroxidase-like activity. In this study, hydroxyl radicals (• OH) generated by MNPs-catalyzed degradation of H2 O2 converted the N,N-dimethyl-p-phenylenediamine (DMPD) probe into its colored DMPD•+ radical cation, which gave an absorbance maximum at λ = 553 nm.
