Paramagnetic properties and antioxidant activity of metal-containing bionanocomposites based on humic substances

Paramagnetic properties of novel bioactive nanocomposite materials based on humic substances and the precious metals (Ag, Au) are investigated by electron paramagnetic resonance and compared to their antioxidant properties. The possible mechanisms of antioxidant activity in the light of the free radical activation or inhibition of oxidation processes are analyzed
