Detonation nanodiamonds as antioxidants in various test systems

Abstract

Detonation nanodiamonds (DND) are shown to exhibit antioxidant activity both in vitro and in vivo. DNDs, when introduced into laboratory animals by oral delivery, decrease protein peroxidation in erythrocytes, inhibit peroxidation of lipids and proteins in blood plasma. In case a pro-oxidant, NaNO2, is administered to animals, DND also protects them against the chemically induced oxidative stress. The results of the testing provide the experimental basis for recommending DND as a potential antioxidant for correcting oxidative damage of different origin.
