Peroxidase‐Like Activity of Cupric Oxide Nanoparticle

It′s a mummers catalyst: Upon the addition of cupric oxide nanoparticles to the peroxidase substrate TMB in the presence of H2O2, a blue color product can be formed with a maximum absorbance at λ=652 nm, indicating that cupric oxide nanoparticles have peroxidase-like catalytic activity.
