<p>Provided is an antioxidant or oxidation inhibitor made using a surface-functionalized nanodiamond compound. The compound comprises functional nanoparticles resulting from the chemical modification of the nanodiamond surfaces. The antioxidant effect has been measured using the oxygen radical absorbance capacity (ORAC) method. The compound has been confirmed to have an antioxidant effect overall, albeit that some variation exists depending on the chemical structure of the moiety which is chemically bound to the surface of the nanodiamond. More particularly, a nanodiamond compound having an amine group has exhibited an ORAC value which is 25 times the level of vitamin C at the same water concentration. The nanodiamond compound enhances the antioxidant properties of water, soft drinks, alcoholic drinks, foods, cosmetics, medicinal products, edible fats/oils or grains, or can be used in order to prevent oxidation of industrial oils, polymers, ceramics or metals (Figure 7).</p> |
