Stability of silver-containing nanocomposites, synthesised from medicinally promising humic substances, has been studied. The nanocomposites obtained possess aggregative stability and conserve their properties for a long time. All compounds have been investigated by physical and chemical methods including electron paramagnetic resonance, plasmon absorption spectroscopy and X-ray diffraction analysis. It is shown that unlike the composites synthesised from humic substances of deeper decomposition, in natural macromolecular matrixes of nanocomposites formed from mud and shale humic substances both 6–14 nm nanoparticles and silver clusters Ag n are generated and stabilised.
